The following bug has been opened against rfc3261. http://bugs.sipit.net/show_bug.cgi?id=769 > 2) I have read somewhere that UAS can start sending media > after sending 200 OK. Shouldn't UAS always wait for ACK > before actually start media ? The endpoint can do whatever it wishes. However to avoid clipping, devices which stream recorded messages typically wait for ACK or delay a short period time before streaming the media. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
