Bug#575465: asterisk: voicemail hangs in vm-intro before the beep unless "s" flag is used

[Alex]

Package: asterisk
Version: 1:1.6.2.2-1
Severity: important
Tags: sid

Calling an almost stock config asterisk configured with unlimitel.ca's configs generated here:
http://www.unlimitel.ca/temp/support/voip_support/voip_configuration_samples.html
and just adding a VoiceMail(2102) after the Dial in the incoming section of extensions.conf.

the vm-intro starts and then cuts around 6-7 seconds in and we never hear the beep and the voicemail is thus never recorded.
On a 2nd try (and any other after that) it'll cut after only 1-2 seconds...

using the "s" flag, i'm able to leave a message but this makes using the voicemail for strangers very awkward.

This bug showed up, without any config change, at some point while upgrading past the firsts 1.6 releases (maybe around 1.6.1 can't remember!).

So I don't think it's strictly 1.6.x related? Maybe I'm wrong but 2 different config give the same result. (see bellow)

I also get the same result with language=en or 2 different "fr" sets of voices.
