This is a general question, so you can get a general answer only:

Telephony Signalling in the sense of SS7/IP does only run over SCTP, as all
SIGTRAN layers require SCTP.

SIP/UDP has some problems. For example with long SIP messages requiring
IP fragmentation.

If you use SCTP or TCP depends on the fault tolerance you want. SCTP supports
multihoming and multiple streams, TCP not.

Best regards
Michael

Hi everybody,
I have been reading about how useful is to transport SIP over SCTP, but I can't find any argument about why SCTP over TCP and UDP for TDM and IP telephony should be a better option. Besides I also read that SIP has its own transport mechanism, but I don't know if it is an efficient one. Do you think that SCTP will displace TCP and UDP for telephony signaling? and Why so?
