Re: [reSIProcate] What is status of first InviteSessionHandle ifonNewSession(ClientInviteSessionHandle) fires a second time?

Thanks for the prompt answers, Scott.

This fix works, except I had to test against 'h_To' instead of 'h_From.'

Will this make it's way into STABLE, or just HEAD? Cheers,

Let me know if that fixes the problem for you.  If it looks good, I'll commit to SVN.

Subject: [reSIProcate] What is status of first InviteSessionHandle ifonNewSession(ClientInviteSessionHandle) fires a second time?

Hi,

Please consider the following scenario:

- my reSIP app sends out INVITE, and receives a 18x response that has no To tag

- onNewSession(ClientInviteSessionHandle cis, ...) UAC callback fires

- my app caches CIS, and also caches InviteSessionHandle learned via CIS->getSessionHandle()

- my app receives 200 response with a To tag

- onNewSession() fires again with different  ClientInviteSession and InviteSession handles.

Leaving aside for the moment  the question of whether the far-end behavior is 3261 compliant:

Q1 - what should my app do with the first set of handles - are they simply obsoleted?

Q2 - Is it an error to continue using them?

Q3 - How do they get cleaned up?

Thanks,
