Nortel CS1K converge SIP with IPC system problem

[boss1987]

The problem about call transfering
that when transfer call from CS1K to IPC some call can 2-communicated and some call can only heard on IPC.

seeing the SIP packet that will send media Attribute (a):sendrecv on call that can communicate 2-way. but it will send media Attribute (a):recvonly on call that can communicate 1-way.

so now I don't know why CS1K send recvonly in second SDP INVITE.
Have someone know about this.

The IPC can support hoot & holler or broadcast lines and I know these either don't send an invite or a different one. Check the trunk config on the IPC.

Biglebowskis Razor - with all things being equal if you still can't find the answer have a shave and go down the pub.

All SIP is not created equal. If you are trying to interop a 3rd-party SIP device with a CS 1000 which has not expliectly been tested and documented via

http://www.avaya.com/devconect,

then all bets are off on interworking.

I'm cs1k implementation team not part of IPC.
But IPC team ask me why CS1000 send "recvonly" in SDP.
I just want to make sure that CS1K doesnot misconfiguration and tell IPC team what they shuld fix.

First thing I should do is tell IPC team to check the trunk config ,right?
