[asterisk-users] Sound problem with format files but not codecs

[Binan AL Halabi]

Hello,

It means that one of clients, is using 'silence suppression' mechanism 
which sends audio frames that do not contain any samples.
Asterisk complains about silence supression and appears these warnings on  CLI.
If the client turn off the silence suppression the message will disappear.

Hi all,

on asterisk 1.8.16

[2012-10-20 19:36:17] VERBOSE[743] pbx.c:     -- Executing [801 at OFFICE-Numbers:2] MusicOnHold("Local/801 at OFFICE-Numbers-e54a;2", "") in new stack
[2012-10-20 19:36:17] VERBOSE[743] res_musiconhold.c:     -- Started music on hold, class 'TOOTAi', on Local/801 at OFFICE-Numbers-e54a;2
[2012-10-20 19:36:17] WARNING[742] translate.c: no samples for ulawtolin
[2012-10-20 19:36:21] VERBOSE[742] pbx.c:   == Spawn extension (from_to-OFFICE, 801, 23) exited non-zero on 'SIP/8081773619-00002f28'
[2012-10-20 19:36:21] VERBOSE[743] res_musiconhold.c:     -- Stopped music on hold on Local/801 at OFFICE-Numbers-e54a;2

or asterisk 10.8.0

    -- Executing [801 at macro-GeneralNumbers:1] Set("SIP/105-00000081", "CHANNEL(musicclass)=TOOTAi") in new stack
    -- Executing [801 at macro-GeneralNumbers:2] MusicOnHold("SIP/105-00000081", "") in new stack
    -- Started music on hold, class 'TOOTAi', on SIP/105-00000081
[2012-10-20 22:48:48] WARNING[22435]: translate.c:343 framein: no samples for g722tolin
    -- Stopped music on hold on SIP/105-00000081

This is when calling extension:

exten=>801,1,Set(CHANNEL(musicclass)=TOOTAi)
exten=>801,n,MusicOnHold()
exten=>801,n,Hangup

What does mean those WARNINGS and how to solve this problem?

MeetMe, Voicemail or holding a call are working fine. From what I understand, codecs are used in channels and format for handling files. In both cases, two different servers, asterisk is compiled from tar.gz and in menuselect all codecs and formats are activated.

Is this a bug? Did I forget something?

On a third server I run latest Elastix with an asterisk 1.8.16 version. On this server I have no MusicOnHold at all even during calls. Logs show

VERBOSE[19717] res_musiconhold.c:     -- Started music on hold, class 'default', on SIP/104-000000b3
VERBOSE[19717] res_musiconhold.c:     -- Stopped music on hold on SIP/104-000000b3

which is MusicOnHold stop immediately.

On all servers wav files are installed, even try with original ones delivered with Asterisk.

Thanks for any hint

Regards
-- Daniel
