[Asterisk-Users] Re: Problem with call hold

FYI, I just download the latest stable version from CVS and the problem is
gone.

Subject: Problem with call hold


I got a very strange problem with call-hold function.

For calls that come in from PSTN and route to a SIP extension.  If I put the
call on hold, I cannot unhold the call after.  The caller would be left with
hold music forever.  A warning message would be shown on the console usually
a few seconds after putting the call on hold:

WARNING[17428]: chan_sip.c:686 retrans_pkt: Maximum retries exceeded on call
0457bd4153a66af6241b2ce5217e823 at 192.168.0.3 for seqno 2079 (non-critical
Response).

The same unhold function works fine for calls between SIP extensions.

I have searched through wiki but could not find the answer.  If somebody can
shred some light on the problem, it will be very much appreciated.

I'm running the Asterisk stable version at Dec 21, 2004.

Thanks ahead.
