Hello,
I am troubleshooting an issue with the calling party name missing from analog phones caller-id causing the phone to display unknown name or out of area for the calling party information.
The setup is as follows: PSTN PRI---3825---(MGCP)---CUCM---(SCCP)---VG224---FXS port. CUCM version 6.1.3
Telco is providing the calling party number in the SETUP message which is being forwarded to the VG224 analog port fine. However, the issue is the telco is not providing the calling party name until the FACILITY message. Once FACILITY arrives, CUCM already routed the call to the analog phone with missing calling party name information which causes the unknown name information to be displayed by the VG224 connected phone. TAC is suggesting converting the MGCP gateway to H.323 gateway but this will add additional management and monitoring issues.
Telco says that they cannot add the calling party name to the SETUP message.
Has anyone else ran into this problem and if so, is there any way to fix this issue without doing a conversion on the gateway?
sh run of the PRI and debug output below:
interface Serial0/0/0:23

Unfortunatly No, we discuss this with De time ago and problem is Call Info message once is recieved by the VG224 cannot be updated with new Call info message after ISDN Q931 Facility arrives.

The feature you're needing to use is documented here:
http://www.cisco.com/en/US/docs/ios/12_4/12_4x/release/notes/rn2800xw.html#wp363697
I do not believe that MGCP has this capability. This is probably why TAC is suggesting a change to H323.

It definitely does...next questions.
1) Is it possible for the Telco to send the calling party name in the SETUP message or is that something that the protocol doesn't support?
2) Do you think that having an MGCP gateway send the calling party name from the FACILITY message would be something that could be supported in a future release?

It is normally sent in the SETUP message. To do otherwise is abnormal, and which is why we have a new feature to support it in the facility message afterwards.
I don't currently know of any plans to implement that in MGCP. If you would like to have this changed, you can talk to your account team to have a feature request filed.
