[SIPForum-discussion] Call with a Invite after 200OK

[AMIT ANAND]

Hi Guilermo,

You need to check with the UAS to know why they are sending 500 for a
reinvite.
Vijay Tiwari is absolutely right here , IF UAS does not like changes in SDP
it should send 488 instead of 5XX.
To me it seems like due to this Re Invite UAS goes to some unknown state and
since it does not able to process this in first clears the Transaction with
500. And after that clears the Dialog with Bye.
To get the reason for 500 you would have to talk to the Vendor of IP
216.82.110.165, only they can confirm the exact reason.

Cheers
Amit Anand
