FreePBX - SMS and MMS Configuration

After spending almost a month getting basic inbound and outbound calls to work, I’m moving to the next major task - enabling SMS and MMS. From what little I’ve red online, FreePBX supports SMS if you’re using SIPStation (SIP trunk) and Zulu. My current SIP trunk is through VoIP.ms, and I followed this documentation:

However, I now have more questions than answers. After performing the configuration changes, I am still in a position where I can only send/receive text messages through VoIP.ms’s web interface. I can’t do so via my current softphone. I feel like an idiot who’s missed something obvious, and even VoIP.ms’s online customer service wasn’t quite able to demystify this for me. I was hoping to port my Google Voice number over, but I can’t do so if I lose this functionality. I also saw this post:

I was unable to replicate their success. During my online search, I ran into a few projects for self-hosted SMS gateways. They all look cool, but I don’t know if those will be of much use to me. Isn’t VoIP.ms acting as my SMS gateway in this scenario?

How can I send/receive SMS and MMS, without using VoIP.ms’s web interface?

Have you reviewed your logs to see what is happening when you attempt to send a SMS?

I will pull those up as soon as I have free time today, and post them as a Google Drive share link. Stay tuned.

Please share via pastebin. (pastebin.freepbx.org)

I’ve created a few unlisted pastebins, which is good until 365 days from now, that can be viewed here:

I own/use all phone numbers listed in the logs. I placed one test call to myself, to make sure my trunk and outbound route works.

EDIT: Just minutes after posting those pastebin links, I received 2 calls from one of my DIDs that I don’t remember placing. I may need to remove these pastebin links once we’ve figured this out.

Can you please explain what happened in these logs?

It looks to me like a misconfigured using from-internal instead of from-pstn and then something is setting the context to ast_msg_queue. So if I am reading this right, it looks like you are receiving an SMS to the from-internal context which tries to place an outgoing call.

Follow the VoIP.ms wiki and it should work fine, if it doesn’t report back with logs.

I will address each of your points:

  1. I cannot fully explain what happened in these logs. That is part of the reason I asked for help.
  2. Your explanation indicates that you know more about this than I do. I will use this info later today, when reviewing my FreePBX config.
  3. I linked 2 articles from the VoIP.ms Wiki, in the OP. I used those to get to where I am now.

This step doesn’t seem to have worked:

The initial context should be sms-out (not any of the others listed above). Are you actually using chan_pjsip on the incomng side?

Here is a screenshot of the config I used:

If something looks off, let me know. I’ve tested it with both extension name and DID number, to no avail.

I think so. That’s the only option I’ve been using during my setup (SIP trunk, outbound/inbound rules, etc.) thus far. I’ve heard of chan_sip, but I think that’s legacy/deprecated (not viable for use).

You need to set here the extension number from where you send SMS from

And repeat that for every extension that can send SMS.

FreePBX, a normally used, expects endpoint names to be the same as extension numbers, as you would dial them, and, unlike Asterisk, uses extension to refer to both of them.

Glad that I kept it simple and have only added one extension so far (0001). The instructions from VoIP.ms made it sound like they wanted either a DID number or the Extension’s alphanumeric Name/ID. Testing that change now:

Still didn’t go through :slightly_frowning_face: I know that SMS/MMS is enabled for my DID. It looks like Google Voice and VoIP.ms are fine. Still not sure about FreePBX config. Here’s what I’ve got so far…

I think it looks way shorter than the previous attempts, but I don’t know if that’s a good thing or not.

EDIT: Just found this link. Have you seen this info before?

“>” is not a valid character in a URI.

This appears to be an error in the instructions from voip.ms. They may have used <…> to indicate a meta name, then thought that might confuse, but missed the closing >, when removing the brackets. Most people would have corrected the error themselves.

I apologise for not seeing that until now. I will try removing that, and let you know how it goes.

After removing the syntax error, outbound SMS (from MicroSIP, through FreePBX) now works. But inbound SMS does not. Halfway there :smiley:

Can you please share an inbound trace?

I’m not sure if this counts exactly as an inbound trace. I sent an SMS to my DID, from my Google Voice number, and grabbed the resulting Asterisk log lines.

I’ll be reviewing this, to see if I can figure out where I tripped up.

Turning on pjsip logger and re-sending test SMS, to see if I can get more log info…
