asterisk users - Sep 2008 - Call-leg stays on MusicOnHold forever

Hi

I have a strange behaviour; perhaps someone who had a similar issue
can help.

I have an Asterisk-1.4.21.2 connected via sip trunk to a Cisco Call-Manager
6.1 cluster.
Two phones/users from the Cisco environment call extensions on the Asterisk.

Phone 1 / Call 1 is parked on the asterisk using:
exten => xyz,1,Answer()
exten => xyz,n,Set(PARKEXTENSION=555)
exten => xyz,n,Park()

Phone 2 / Call 2 is picking it up:
exten => xyz,1,Answer()
exten => xyz,n,ParkedCall(555)

so far so good, they can talk to each other.

Now if one of them presses Hold, Asterisk will:

[Sep  5 14:16:05] VERBOSE[6351] logger.c:     -- Started music on hold,
class 'default', on SIP/10.16.17.162-081bb720
[Sep  5 14:16:05] VERBOSE[6351] logger.c:     -- Stopped music on hold on
SIP/10.16.17.162-081bb720
[Sep  5 14:16:05] VERBOSE[6351] logger.c:     -- Started music on hold,
class 'default', on SIP/10.16.17.162-081bb720

start - stop - start
strange, but it works ...

If the same user/phone now presses hold/resume so that they could
talk to each other again Asterisk does:

[Sep  5 14:16:07] VERBOSE[6351] logger.c:     -- Stopped music on hold on
SIP/10.16.17.162-081bb720
[Sep  5 14:16:07] VERBOSE[6351] logger.c:     -- Started music on hold,
class 'default', on SIP/10.16.17.162-081bb720

stops the music and starts it again ...

now the guy who pressed hold at first can hear the other party, but the
other party only hears music from Asterisk.

Has anyone had a similar phenomenon?

Regards,

Andreas

Andreas,

We can't help, but just to say that after 2 weeks of debugging, we have
found yesterday that the one way audio experienced by the agents some
times, is related to hold function.
