One DID | SMS to Extension | DID to Ring Group

[sheadyman1]

With Inbound rules, it was easy to add the same DID to the SIP Trunk, one with the number (7145551212) and the other with *number (*7145551212). I would then add the number to an extension so that SMS messages would flow to an extension directly and asterisk for the same number to a ring group. The asterisk would then be associated with the ring group while SMS messages would continue to flow to the Ring Group instead. How might I have a DID ring to a ring group while sending SMS messages to an extension with v20?

Firstly, please ensure that the DID is in E164 format (+1234567890) for SMS functionality.

You can route DIDs to an IVR, allowing callers to choose options for the voice call while configuring the SMS to be routed to a different destination if needed.

For more details, please refer to this guide: 3CX IVR Configuration Guide.

Hey Charles, Thank you for your quick response. Bandwidth has instructed us to use a 10 digit rather than E164 format. When I was with Telnyx, we used E164. Not sure why. Maybe I misunderstood. At any rate, I have read enough of your responses to know that you know what the heck you are talking about so I followed your advice and removed the 10 digit DIDs from the SIP and added the E164. I then assigned the asterisk 10 digit DIDs to the digital receptionist and the the E164 (+1##########) equivalent DIDs directly to the extensions for SMS and it worked like a charm.

Curious with regards to why that works. Does the order of the DIDs in the entered into the SIP channel for Bandwidth matter or did this work simply because the 10 digit DIDs threw off the automatic inbound routing with version 20?

I'm VERY surprised that you've already managed to get SMS working with 3CX v18 (or v20) using a 10-digit number without the +1. It's more likely that one of the numbers was in +E164 format and the other with a star ( * ). This method might have worked in the past.

That said, what 3CX recommends is to configure Bandwidth so that both calls and SMS are sent to 3CX in the +E164 format, starting with +1 in your case. Afterward, it's the IVR that handles routing the SMS to the desired destination, the same goes for calls. Thus, think of the IVR as having 2 InboundRules. The DID is pointed towards this IVR and depending on whether it's Voice or SMS, the action may differ.
