Hi people,

I am trying to search for the RFC behavior in case of 180/200 to tag mismatch of an INVITE. >From my readings so far, I'm not 100% convinced of the correct behavior.

However, there may be a scenario, where this might be plausible:

1. parallel forked two calls

2. 180 ringing comes for first one, but not for second one(various reasons)

3. 200 ok comes for second one

Any opinions about this? Do you have some references that will make this 100% clear?

Thank you,

Stefan
