Problem: G729 Codec Translation Path

Asterisk Asterisk Support
1

Hello friends.

I am currently running Asterisk 1.8.15.0 (elastix flavor).
I recently started having this problem with one of my SIP trunks, inbound calls are answered but the inbound caller hears no ringing prior. Also when put on hold, the inbound caller hears no hold-music.
This started happening after a reboot.

My trunk is setup as follows:

username=someuser fromuser=someuser type=peer secret=somepass port=5060 fromdomain=somedomain host=somehost defaultexpiry=3600 dtmfmode=rfc2833 canreinvite=no insecure=very disallow=all allow=g729&ulaw&alaw sendrpid=yes&pai nat=yes

Everything is registered and like I say, we can make inbound and outbound calls.

The logs for the inbound calls show:

My g729 codecs are registered:

[code]0/0 encoders/decoders of 4 licensed channels are currently in use

Licenses Found:
File: G729-somenumbers.lic – Key: G729-somenumbers – Host-ID: somenumbers – Channels: 4 (Expires: 2032-03-20) (OK)[/code]

My output on the asterisk cli for core show translation:

[code]Translation times between formats (in microseconds) for one second of data
Source Format (Rows) Destination Format (Columns)

Anyone know why this could be happening?

EDIT

I did a reload of the module from the cli and ringing was restored. The output from core show translation now shows values for g729.

I am now working on why my hold music isnt playing.

EDIT

MOH for some reason was reset to “none”. Fixed that the que settings. All good now.

I suddenly ran into the same issue. what command did you issue to “reload the module” in the cli?

Module reload codec_g729.so

Thanks again navaismo,

for me it’s “codec_g729a.so”
