After many days banging my head against the wall I've manged to get a Panasonic NCP 500 and a Cisco 2811(running c2800nm-adventerprisek9-mz.151-1.T) and CCME 22.214.171.124 to call each other over H323.
Now the call works both ways however I'm unable to get the Calling Name displayed in either direction. After many hours researching this on the net it would seem that it's because the calling display is populated in an ISDN messages in the Display Information Element (IE) of the Q.931 Setup packet.
The following commands appear to resolve this on a serial interface :
voice service voip
h225 display-ie ccm-compatible
isdn supplementary-service name calling
However unfortunately "isdn supplementary-service name calling" is not supported on Fast Ethernet ports. Does anyone know of another way of getting this information to display as I've got 99% of the functionality working now and this wold be the icing on the cake?
Many Thanks in Advance
