Hi. Please let's forget "SBC" and let's go to a simpler case: a PSTN
provider that speeak SIP and RTP with clients and SIP/SS7/ISUP with
other PSTN operators. The signaling and media conversion is done in
PSTN gateways. Most of them, for sure, don't implement ICE neither
SRTP.

Anyhow, concerning this subject, I already proposed something in other
thread: why couldn't the provider (the web site) tell their WebRTC
clients wheter they shoud or not accept media sessions without ICE
and/or SRTP?

For example, a telco operator that creates a web site for allow its
clients making PSTN calls from the web, could relax those requirements
and don't mandate ICE/SRTP. In the other side, a social network web
site which just allows calls between web users could mandate them.
Such configuration could be retrieved by the WebRTC client via HTTP or
WebSocket by standarizing a document format.

Regards.
