# Dial Out Email Notification to SMS: Send PBX Alerts as Text Messages

Dial Out Notification watches your extensions and fires an alert when someone dials a number on your hot list, or when a call gets transferred to a trunk outside the groups you defined. It runs alongside Panasonic KX-TDA, TDE, NCP, and NS phone systems.

The text alert has to reach somebody. Out of the box that means a message on a desk phone, an email in an inbox, or a text message. The text is the one people actually see, and it is also the one that costs the most, because the software needs an external cellular modem to send it. A box with a SIM card, a serial cable, and a monthly plan.

Plenty of sites skipped that expense and pointed the Mail column at a carrier gateway address instead. Those gateways are gone or going.

So most sites running this software now sit in one of two positions. Paying for hardware they do not need, or running alerts that quietly stopped arriving. Dial Out Notification email to SMS fixes both using the Mail tab the software already has.

## Are Your Alerts Going to a Dead Carrier Gateway?

Check your alert rules before making any other changes. If any address in the Mail column ends with **@txt.att.net, @vtext.com, or @tmomail.net**, those notifications may no longer be reliable.

[AT&T closed its gateway](https://textbolt.com/migration/att/) on June 17, 2025. [T-Mobile’s tmomail.net went effectively offline](https://textbolt.com/migration/tmobile2/) in December 2024. [Verizon email to text](https://textbolt.com/migration/verizon/) has been degrading since late 2024, with full shutdown expected by March 31, 2027.

The failure mode is what makes this worth checking today rather than next quarter. Dial Out Notification logs the email as sent, because from its side it was sent. Nothing comes back to tell you the person never received a text.

That silent pattern is exactly what caught out the legacy systems described in our [AT&T and Verizon email to SMS shutdown](https://textbolt.com/case-study/verizon-att-email-to-sms-shutdown-legacy-iot-migration/) case study, where dashboards stayed green while alerts went nowhere.

If your last real test was more than a year ago, assume it is broken until you prove otherwise. Fixing it means replacing that address, which the setup section covers.

## Who Uses Dial Out Notification and What Do They Watch?

Dial Out Notification turns up across a wide range of sites. Informal call centers, public institutions, law offices, retail, construction, and manufacturing. Also [utilities providers](https://textbolt.com/industries/utilities/), rail and bus operators, airlines, ferry and cruise lines, telecom operators, and marketing research firms.

What they have in common is a switchboard with a lot of extensions and a short list of numbers somebody wants to know about.

Common rules include watching for calls to expensive international or premium rate destinations, watching a specific internal line so a supervisor knows when it is used, and catching call transfers onto trunks outside the permitted groups. Utilities and transport operators tend to watch dispatch and control room lines, while [government agencies](https://textbolt.com/industries/government/) often watch a small set of extensions rather than all of them.

One boundary matters, and the vendor states it plainly. This software cannot be used as a primary 911 notification service or as a primary alarm handling device. If emergency notification is what you need, that requires a purpose built system, and this is not it.

## Why Does the Cellular Modem Path Cost So Much?

The SMS tab asks for a COM port, connection speed, data bits, parity, stop bits, and flow control. Those are serial cable settings, and they exist because the software does not send texts itself. It hands the message to separate hardware and lets that device do the sending.

That hardware carries costs the software price does not show.

| **Feature** | **Cellular modem path** | **Email path with TextBolt** |
|---|---|---|
| Up front | Modem, SIM, cable, often a serial adapter | Nothing to buy |
| Ongoing | A mobile plan that never ends | Message credits only |
| Recipients | One device sending sequentially | Every address on the list, at once |
| Record of what was sent | None outside the software log | Every alert in your inbox, timestamped |
| When it breaks | Silent. Looks identical to working | Visible in your mail server and inbox |
| Physical dependency | A box in a closet | None |

The failure row matters most. If the modem gets unplugged, the SIM expires, or the signal is weak where the box lives, the texts stop and nothing announces it. A modem that died six months ago looks exactly like one that is working.

Replace Your Cellular Alert Hardware

Send Dial Out Notification alerts to staff phones as SMS using the email setup you already have. No modem, no extra hardware, and no complicated setup.

## How Does Dial Out Notification Email to SMS Work?

Dial Out Notification can already send email, and at most sites that feature is already configured. Rather than adding a delivery method that needs hardware, you use the one that works, which is the same method behind any setup that can [send email to text](https://textbolt.com/how-to/send-email-to-text/).

In your SMS alert rule, instead of typing a person’s email address, you type a phone number written to look like an email address. The software cannot tell the difference. It sends an ordinary email, exactly as it always has.

TextBolt receives that email and delivers it to the phone as a real text message. This mirrors [IT alert text messaging](https://textbolt.com/industries/it-departments/) from server monitoring tools, and it works for the same reason. Nothing gets rebuilt.

Both the subject line and the message body become the text, which changes how you fill in those fields.

There are three parts to this. You set up email once, you change a few fields in each alert rule, and then you test it.

Nothing gets installed along the way. Your phone system, your license, and your existing rules all stay exactly as they are.

**Set up once: the Mail tab**

Open the Mail tab. It asks for a mail server, a port, and a From Address, the same details you would use to add a work email account to a phone. Your IT person or email provider will have these.

Press Send Test E-mail to check it works, then press Apply to save. Both buttons matter, and skipping Apply is an easy way to lose the settings.

Then register that From Address with your TextBolt account. Alerts sent from an unregistered address get rejected, and nobody hears about it.

**Then, in each alert rule**

Alert rules live in the Users Action tab. Each row across the grid is one complete rule, and it reads left to right as a sentence: watch these phones, for this number, tell these people.

One thing surprises people here. The grid looks like a spreadsheet, but you cannot type into the cells. Click a cell and a Browse button appears inside it.

Click Browse and a small window opens. Enter your values there, one per row, pressing Enter after each, then click OK to close it. That is the pattern for every column below.

| **Column** | **What to put in it** |
|---|---|
| Mail | +15551234567@sendemailtotext.com, one row per phone |
| E-mail subject | Something short, like **Intl call ext 214** |
| SMS | Leave empty |
| SMS Text | Leave empty |
| Time Range | Full Time, a set period all week, or a period on chosen days |
| Rules | Allow to be told only, Reject to block the call too |
| Rule Type | Outbound, for calls leaving your extensions |

Write the address as **+1** and then the ten digits, no spaces or dashes, so the example above reaches 555-123-4567. Replace any dead carrier gateway addresses while you are in there.

Keep the subject short, because it is not really a subject anymore. Subject and body both become the text, so whatever you type there becomes the opening words of the message.

Leaving SMS and SMS Text empty is the part that retires the modem.

**Then test it**

Dial a watched number from a monitored extension and confirm a text arrives. The History tab logs each delivery method separately, so you can see which ones succeeded rather than guessing.

## What Can the Email Path Do That a Modem Cannot?

Dropping the hardware is the obvious win. The less obvious ones make this worth doing even where the modem currently works.

- **Everyone gets told at once:** A modem sends to one number at a time. The Mail column takes as many addresses as you need, and every phone receives its own text independently. Adding somebody is typing a row, not reconfiguring hardware.
- **You get a record:** Every alert lands in your inbox with a timestamp and delivery status, searchable alongside everything else. When somebody asks later what was sent and when, you have it. The modem leaves nothing outside the software’s own log.
- **Messages route as business traffic:** TextBolt sends over registered A2P 10DLC routes, which supports up to 98% delivery.* Carriers recognise that traffic as legitimate rather than filtering it. A consumer SIM in a modem gets no such treatment.
- **Changes take seconds:** Different supervisor this month? Edit the address. New site opening? Copy the rule. It is the same principle behind any workflow that can [send text with no code changes](https://textbolt.com/blog/send-text-no-sdk/), applied to a phone system instead of an application.

## Where Does the Email to SMS Path Fall Short?

Three things are worth knowing before you move your alerts to email.

- **The email path is US and Canada only.** TextBolt delivers to those countries. A modem with a local SIM will still reach staff phones anywhere, so overseas sites should keep the hardware.
- **Every repeat costs a credit.** Alerts fire at set intervals until handled, and each repeat sends another text. A modem on a flat plan absorbs that. Credits do not. Check your repeat interval first.
- **The email path leans on your mail server.** If it goes down, alerts stop. That is a real dependency, traded against a box in a closet that fails silently.

Everything else the software cannot do, it could not do with the modem either. Emergency notification, two way replies, and anything outside the two triggers are limits of the application, not of how the message travels.

## When Should You Make the Switch to TextBolt?

The software already knows how to raise the alarm. Everything in this guide is about where that alarm ends up, and the answer turns out to be a TextBolt address in the Mail column rather than a purchase order.

If the modem is working and already paid for, there is no rush. Make the change when the SIM comes up for renewal and skip the next bill.

If it has failed, or the Mail column still points at a dead carrier gateway, adding a TextBolt address takes minutes. Your rules, your license, and your phone system all stay exactly as they are, and there is no hardware to order or return.

Whichever applies, test it before you trust it. Dial a watched number and confirm a text lands on a real handset. An alert nobody receives is worse than no alert at all, because you believe you are covered.

The TextBolt trial runs seven days on ten credits, which is enough to fire a few test alerts and watch them land on a phone.

And if the Mail tab will not talk to your mail server, [contact us](https://textbolt.com/contact/) before giving up on it. On software this old, that is usually an app password, not a dead end.

## Frequently Asked Questions

** Do we have to reinstall or update the software?**

No. Your phone system, license, and installation stay exactly as they are. You add an address to the Mail column of a rule that already exists. There is no downtime, nothing to install, and no site visit needed.

**Do we still need the cellular modem?**

No. The modem exists only to serve the SMS and SMS Text columns. Leave both empty, use the Mail column instead, and you can retire the box and cancel its monthly plan.

**How do I test that alerts reach phones?**

Dial a watched number from a monitored extension and confirm a text arrives on the handset. Then open the History tab, which logs each delivery method separately, so you can see which ones succeeded rather than assuming.

**Can different people get alerts at different times?**

Yes. Create more than one rule and use the Time Range column on each. One rule can text a supervisor during business hours, while a second texts whoever is on call overnight and at weekends.

**Will this work with Gmail or Microsoft 365?**

Usually, though older software sometimes needs an app password or an internal relay because of stricter modern security rules. Test with the Send Test E-mail button before relying on it for live alerts.
