So should the CANCEL request have both the From & To tags, or just the From tag ? I believe that both should be sent, because the full Dialog related information could be available from the received provisional response (s.a. 182 or 183). [ABN] the CANCEL request may optionally contain the to-tag. Since 100 Trying response may not carry the to-tag. If some 1xx response received which carried to-tag, this tag might be put in CANCEL request, but none of the intermediate entities or servers mandate the presence of to-tag in CANCEL request processing...... thanks for any clarification. regards, bdutta _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
