You can get the peer's signalling IP address from ${CHANNEL(recvip)} and the RTP address with ${CHANNEL(rtpsource)} resp. ${CHANNEL(rtpdest)}.
If you need more information (like the codecs used) you can find other channel variables on https://wiki.asterisk.org/wiki/display/AST/Asterisk+11+Function_CHANNEL

Please note that, if you have not disabled re-invites, the RTP address may change while the call is running.
