> In the following call flows which transport layer > protocol should be chosen?
The following is the relevant contact. Contact:<sip:as.iop2.broadworks.net> As mentioned within rfc3261, rfc3263 should be followed. Thus the transport is determined by NAPTR or SRV records. If they do not exist, the above sip-uri defaults to UDP. Additionally if the request exceeds the path MTU size (as possible within UDP), a more appropriate transport (like TCP) can be tried first. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
