Hi

the silence give a crappy audio on announcement, is therer a possibility
to remove it? Asterisk 22 version.

logs:
– Stopped music on hold on PJSIP/plop2p_104-00000165

               -- <PJSIP/plop2p_104-00000165> Playing

‘queue-youarenext.gsm’ (language ‘fr’)
– Told
PJSIP/plop2p_104-00000165 in q821 their queue position (which was 1)

  -- <PJSIP/plop2p_104-00000165> Playing 'silence/1.gsm' (language

‘fr’)

 -- Started music on hold, class 'myclass', on channel

‘PJSIP/plop2p_104-00000165’

If you remove it, but are still using the GSM codec for the call, it will be transcoded, on the fly, from another format (probably slin). As that is how the .gsm file was created, it might have the seam artefacts. The real question would be why are you using the GSM codec? It is old, there are better low bit rate codecs, and the trend is towards using high audio bandwidths, because bandwidth is no longer a significant issue.

I also tested with g722, same behavior

The playing of silence is not in the code or default. Have you set the “queue-thankyou” option to it? If so and you don’t want a sound file to be played, then you set it to blank:

; Keep in mind that you may also prevent a sound from being played if you
; explicitly set a sound to be an empty string. For example, if you want to
; prevent the queue from playing queue-thankyou, you may set the sound using
; the following line:
;
; queue-thankyou=

Nothing is set. This is my queue conf:

[q821]
musicclass=default
announce-frequency=10
announce-holdtime=once
announce-position=yes
autofill=yes
autopause=no
leavewhenempty=no
joinempty=yes
maxlen=0
periodic-announce-frequency=0
queue-thankyou=silence/1
reportholdtime=no
retry=3
ringinuse=yes
servicelevel=60
;strategy=rrmemory
strategy=ringall
weight=0
wrapuptime=0
setinterfacevar=yes
setqueueentryvar=yes
setqueuevar=yes
timeout=5
member=PJSIP/plop2p_105
member=PJSIP/plop2p_135

Timeout is low as I test the dialplan

You’ve configured it to play silence as the “thank you” sound file after it announces the position.

Oh dear, shame on me, I did read it many times and it didn’t hit my eyes.

Sorry to have bother you, thanks for your support.
