Hi Sunitha, 

 

  This is normal call once the call is connected both the parties try to


Put each other on hold and end up in race condition.

 

Regards, 

Ashok

Hi Sunitha, 

 

This is the real problem I'm facing due to race in the network between
two re-INVITE (hold) received from both the 

one party to other. Basically PRACK is used to acknowledge the data sent
in 1XX reliably.

Regards, 

Ashok

I believe you can probably try with PRACK messages..........

Hi All, 

 

What could be the UA2's SIP response to a hold request when UA2 itself
trying put UA1 on hold 

& hold is in progress(some state in INVITE/200OK/ACK).

 

Race between two hold request.

 

 

 

Thanks &

Regards, 

Ashok
