Is Genband's C20/CS2000 switches used as a gateway to PSTN and SIP network? or
is it used as a pure SIP network element (proxy, B2BUA, etc)?

Yeah, I’m aware of the methods used to support it in SIP, but I’ve never
understood why you would want to. As RFC 3578 states, if there is some switch

Googling for overlap signaling leads you to http://tools.ietf.org/html/rfc3578
and other discussions.

Dear All!
In PSTN networks, it's
Dear All!
In PSTN networks, it's beneficial to try to establish a connection between the
caller and the callee before the full phone number digits are collected. But
SIP works over the connectionless IP network, is there any benefit to use
overlap signalling in a native SIP network?
