hi,
it seems to me that the current sip draft is unclear whether tcp is
mandatory for redirect servers. section 1.5.2 (protocol properties,
lower-layer-protocol neutral) says ...
"User agents SHOULD implement both UDP and TCP transport. Proxy,
registrar, and redirect servers MUST implement both UDP and TCP
transport."
... but section A.1 (minimal implementaion, transport protocol support)
says ...
"User agents and stateless proxies MUST support UDP and MAY support TCP or
other transport protocols, stateful proxies MUST support both UDP and
TCP."
regards,
jakob
