Re: [Astlinux-users] Problems with voicemail and Asterisk 16 on Astlinux 1.4.7

[Michael K. <mic...@ip...>]

Hi Lonnie

Thanks for this.

So the testing I performed was to call into the system from my mobile to a number that goes directly to voicemail without a greeting. If the call stayed up for a couple of seconds then I would hang up and call again.
Whenever I got the Warning messages, the call actually dropped. Another log line I didnt add was:
-- Recording was 0 seconds long but needs to be at least 1 – abandoning

I also posted on the Asterisk forum and someone mentioned that a solution to the problem could be setting “transmit_silence=yes” in asterisk.conf which I tried and it significantly reduced (possibly eliminated) the problem.

I will try setting this at a couple of our problem sites to see if it fixes the problem and let you know how I go.

Regards
Michael Knill

Hi Michael,

I looked through the Asterisk code, this is basic core code, but some 'code stirring' has occurred between 13 and 16.

If you can replicate it in the lab, does Astlinux 1.5.0 / 13se work as expected with your voicemail.conf?

Does the error occur only on long (longer) voicemails?

Does the error occur intermittently or all the time?  Any pattern?

Lonnie
