Subject: Re: [Freeswitch-users] Cisco 7960 has problem with music on hold

Well you seem to have left out some details.

1. SIP Load on the 7960?
2. What Rev of FreeSWITCH?
3. No sip traces.

I know it works on my 7960, 7975, 7965 and others.

I just installed FS and registered two cisco 7960 with default configuration file. They can talk to each other.  After connecting both phones, I can put one on hold with music, but I can not get the connection back by pressing resume softkey button. Once I pressing resume button, the connection was hangup.
I can see the cisco 7960 sent INVITE to freeswith once I press resume button but FS sent back 'SIP/2.0 500 Overlapping Requests ' message. This cause cisco 7960 sent out BYE message.
Any idea?
