CUCM 8.6 -> SIP Trunk -> ISDN GW 3241 -> ISDN Caller ID

Hi,

 

we have recently bought 2 3241 ISDN Gateways. The initial configuration was easy and calls are running in and out. Unfortunately the Gateway doesn't send the calling party number in the correct way to the isdn switch. 

 

For example: A DX80 registered to the CUCM(192.168.1.10) has the number 87654321 and calls 00498912345.

The 3241 ISDN GW dials out to the ISDN and uses 87654321@192.168.1.10 as the calling party number. The ISDN Switch doesn't know the @ sign because it is not valid in the ISDN. 

 

Is there a possibility to cut the calling number before the @ sign?

Is there a possibility to restrict the calling number on the gateway for all outgoing calls? (Settings, ISDN, ->Send calling number to ISDN network never doesn't work)

The gateway uses Firmware 2.2(1.106)P

Thanks in advance!
