UA has sent INVITE to remote party. It received the 100 Trying. Now user wants to CANCEL the call. Can A CANCEL be sent at this point in time or it can not unless some non-100 provisional response comes? Thanks, Isshed. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors "DISCLAIMER: This message is proprietary to Aricent and is intended solely for the use of the individual to whom it is addressed.
