external call forwarding IPCC to external number


A customer of ours is running Cisco Callmanager 4.1(3) and Cisco CRA 4.0.3. When a caller calls after business hours the call is directed to a script on the CRA. When the caller presses 1 he/she is directed to an outside emergency number. But this doesn't work because the Telco only allows calls matching the customers CLI. The call is not forwarded through the Telco's network because the CLI is that of the caller instead of that of the customer.

When I configure a dummy phone with a call forward to an outside number there is no problem. The call is setup correctly and I get to see the CLI form the customer.

We've even tried to forward the incoming call through a dummy phone to a CTI Rout Point but with no results.

Does any one have any idea how we can change the CLI of the forwarded call so it gets allowed through the Telco' network?

thanks in advance,

Re: external call forwarding IPCC to external number

Downgrade to Cisco IOS Software release 12.3(7)T1. This interoperability problem has been reported in 12.3(8)T images only.

Do not use the dialplan-pattern telephony-service command.



Re: external call forwarding IPCC to external number

(since i see no IOS device in your configuration you mention, the above response may not apply)

perhaps you can build a translation pattern that will match all inbound calls to the IPCC RP. this translation pattern can have the "callingNumber" digits setup to what the telco permits.

when ivr needs to forward off premise, it sends call back to icm which will send it to ccm. the xlation pattern calling digits should now be in the form of what the telco permits.

(this of course creates the problem of now not seeing the correct calling number digits if the call does not need to go off prem.)
