I need information required Asterisk supports BICC over IP signalling protocol and what variants of SIP asterisk supports
I don’t know what BICC is… or what variants you are referring to. Are you talking about specific RFCs?
Probably referring to https://en.wikipedia.org/wiki/Bearer-Independent_Call_Control
libSS7 doesn’t, as far as I’m aware. And, I don’t know anything about chan_ss7 - any such question about it would be better directed to its maintainers, since it’s not distributed with Asterisk.
chan_ss7 does not support BICC
Its VOIP protocol just like SIP media is delivered using RTP any one can help
