New VitalPBX user with Telnyx - can't get outbound calls working

Hi all,

We are an MSSP evaluating VitalPBX multi-tenant for our clients.

We have it installed on a Hostinger VPS and using Telnyx as our trunk.

We currently have just one IP phone with DID provisioned, a Yealink T54W. Inbound calls are fine and sound great.

Initially, the call was getting rejected by Telnyx - presumably because we forgot to set an outbound caller ID, and this has caught me before on other PBX systems. I addressed this, checked some other things, and finally applied those changes.

However, making an outbound call from the T54W, it just rings and rings without the call actually connecting. This time, strangely, Telnyx debugging shows no call attempt as if the outbound call isn’t even being attempted now.

I’m sure I’m making some basic mistake here. I’ve attached screenshots of the trunk configuration and the outbound rules. Let me know if there’s anything else useful I can grab that might help identify the issue.

Note that I’ve tried with and without the outbound registration client/contacts/server URI field filled in per the recommendation here that fixed someone else’s similar issue on Telnyx. (It did not fix it for me.)

It would help to watch your log file as you’re making the outbound call. Also, if your number profile in Telnyx is E.164 you can probably drop the + in Outbound Caller ID.

I use Telnyx. They started blocking outbound calls from some ID my extensions because they wanted the outbound caller ID as an 11-digit NANP number. Your trunk does not explicitly overwrite the CID, so check each extension and make sure the outbound caller ID begins with 1.
