One way audio ulaw

Summer · February 28, 2022, 8:19am

Asterisk 18.6.0, two sip devices from different brands, both are using:

pjsip endpoints
ulaw codec
ptime=20
no nat
pjsip show channelstats: show no packet lost.

One can hear clearly, the other one is completely muted.

I’ve tried disallow=all and allow=one_at_time_each codec.
But seems that only ulaw is managed by both.

If you make a call to voice mail you can hear and talk correctly from both.
Any idea on how can I fix this?

Thank you, BR

is there a firewall between the two phones? sounds like a NAT issue

Stewart1 · February 28, 2022, 3:07pm

Confirm that Direct Media is set to No. Capture traffic with tcpdump / Wireshark and report whether audio is being sent to both endpoints.

Summer · March 1, 2022, 9:52am

Thanks for the replies, direct_media is set to no on both extensions, there’s no firewall, only LAN traffic.

Extension are:
1110 (ip.19): start the call > hear 1107
1107 (ip.210): receive the call > cannot hear 1110
PBX: (ip.205): Attached packet recorded with sngrep.

Fix info on the first post: Asterisk PBX 16.16.1

Looking with wireshark > voip it seems that there are wrong timestamps and silences, but cannot find any “how to fix it”.

Please rename the PACKET.tgz to PACKET.pcap

Am I missing some informations, to get an opinion about it?

Summer · March 21, 2022, 1:50pm

Anyone has opened the tcpdump?

Can you please point me out, where I can address my question to get an help about it?

Where was this trace taken from? We generally prefer a trace taken from Asterisk’s full log file with “pjsip set logger on” enabled.

It surprises me as It is doing things I wouldn’t expect Asterisk to do. Asterisk appears to be reINVITEing with a changed audio port number, but the same IP address, and rejecting a video stream that wasn’t there originally. I’m much more used to analyzing chan_sip logs, but I’m surprised that chan_pjsip would do this. I’m wondering if the trace is being taken the wrong side of some application level gateway, which is messing things up.

If this is really taken from the Asterisk machine, I would want to turn up the debug level on Asterisk, as well as enabling set logger on.

Thank you for the reply, I’ve recorded the packages with sngrep ( GitHub - irontec/sngrep: Ncurses SIP Messages flow viewer ) this is running on the PBX.
I will turn on the debug and logger and send new log asap.

Summer · March 24, 2022, 2:01pm

New data with asterisk log level set to 6 and record from sngrep, all came from the PBX
