Hi,
Is there a way for a SIP UA to know whether another SIP UA is available or not, without establishing a session? I heard that one can use an OPTIONS method for this. But what if the SIP UA hasn't implemented it and just drops the message without responding? Are there any other ways? Thanks for your help, YoungSun _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
