configuring source address for session target ipv4

unknown

Which interface do I configure as the source address? I have a vwic 1mft1 connected to 2 cme routers. Have it set up as a pri.
Do I assign an ip on port 0/0:23?

nah - you dont assign the IP to the D-Channel interface, those are just ISDN signaling channels - you dont need a voip dial-peer just the pots dial-peer

SCCP phones actually build their own dial-peer internally, so there isnt any voip call legs just the ISDN ones
