Partial failure on outbound calls using Telnyx

[IshavAulakh]

I have been having a strange issue with my FusionPBX installation. For some strange reason about half of my outbound calls are failing on the same SIP trunk ( Telnyx). They have been solid for me for years. Contacted the support on Telnyx and they say the calls i am reporting are not even showing up on there end. Did a live trace as well but to no avail. The same call will terminate fine on a secondary provider. On the active calls list the B leg does not show Codec negotiation.
Stays like that till timeout is reached. The softphone gives a single ring instead of the standard US ring.

Here is my system info:

And here is my Sip status.


Can anyone please help figuring out what may be going wrong.

My guess is that Telnyx changed or added to their signaling IP's for your region and you haven't added the modifications to your firewall whitelist or perhaps your ACL in fusion.

Already confirmed the ACL. Also have a ticket open with them regarding the issue. What i am wondering is can there be a specific issue happening on the bleg codec negotiation?

@DigitalDaz Need some guidance sir. The system is mission critical and i am losing a lot of business. Can you help?

 

[bcmike]

Do you need to use Alaw or can you use Ulaw?

Figured it out. Had shifted the PBX to a vm on proxmox. I think the issue was caused by that. Shifted out to a vps from vultr and things are sorted.

Has anyone had issues with running pbx on proxmox??
