No ringback tone when making inbound call

None

Recently our client has experienced an issue where a caller would hear nothing, no ring back tone, when calling their mainline. When calling it would be quiet until the receptionist answered the call.

They use a MyPBX-Standard V4 and the phone used is a T28P.

A snippet of the logs when dialling in:

I'm not sure if any of that is relevant, but currently I'm stuck on finding a solution for this issue.

Please don't hesitate to ask for more info if you need it.

Thank you in advance

I notice from the logs you post:

Dropping incompatible voice frame on SIP/trunk-sps-2Talk-000001c1 of format ulaw since our native format has changed to 0x8 (alaw)

Please check if you have enable ulaw on your 2Talk SPS trunk, if not, try enable it and see if it helps.

If doesn't help, try capture a pacp logs and post the logs here.

See this article for the guide how to get pcap logs:

Hi Oscar, thanks for the reply!

As seen below, these codecs have been selected already:

I've run the packet capture for 15 seconds while performing an inbound call and received the below results. I've omitted some details, but if you need them please let me know. (E.g: **SparkISP** and {Internal.Network})

The **MyPBX** seems "answer"(by sending 200 OK instead of 180 ringing response) the call before **MyPBX**4 answer the call, so there is not SIP 180 ringing response sent back to 2talk. I have some questions below:

1. What is the inbound route's destination for 2Talk SIP trunk？

2. Is **MyPBX**4 another PBX?

Hi Oscar,

Apologies, when I omitted the data I accidentally gave an internal phone the same false name:

E.g: 10.0.0.22 = **MyPBX** | 10.0.0.224 = **MyPBX**4

In conclusion, **MyPBX**4 is actually the omitted IP address of a phone.

Regarding the inbound route, please see below screenshot and let me know if that's what you're looking for:

FXS Extension:

Can you post a screenshot of your inbound route for 2Talk?

You screenshot you post is SIP trunk page and FXS extension page.

Also, the phone on your pcap logs is 101 but not 601.
