Hi Greg,
this is definatly wrong behavior of the UA because OPTIONS is not part of the call establishing with INVITE and should have a new CSeq.
For our own knowledge base: which UA has such a strange OPTIONS implemetation? :-)
Greetings Nils

I am forwarding the OPTIONS message from the UA to my gateway (cisco 7206 / pa-vxc-2te1+ / sip) and the gateway is returning what looks like the answer to an INVITE request. I have a pretty current gateway. The UA tries over and over sending one after the other OPTIONS messages. I think it doesn't like the reply from the gateway.
What is weird about the OPTIONS request is that it is including the established Callid.
I tried grabbing the message in the Ser proxy and sending a 486 busy.
Thanks for the help. Most UAs do not present any problems, but this one has been very challenging.
