Is it legal to change the contact in a Re-INVITE?
Hi Folks,
I have an odd case with a VCS where we correctly setup the call and then shorlty afterwards a Re-INVITE is sent from one end with a different contact specified. I am wondering if it is legal to change the contact in an established dialogue with a Re-INVITE as I thought it was only possible to change during the 200 Ok.
It seems that this contact change is causing the SBC to not forward the subsequent ACK so the call fails.
Thoughts?
Cheers, Toby
