Question : cisco Call manager express call forward all problem

Hi all,

I am having problem forwarding all calls to a external number. Here is my setup

CSICO 3640 (ISDN lines) -> CISCO 2811 (ip phones 7960)

when i set the "call forward all 90208XXXXXXX" (number hidden purposely), the calls don't go through to the destination.

I have an dial-peer for matching the destination pattern 90208XXXXXXX, in fact when i dial this number from the same extension where the forward is in place the call connects without any problem.

To explain the sequence of the call flow.... a call comes in on ISDN line to CISCO3640 get directed to CISCO2811 and get redirected to 90208XXXXXX but fails.

What am i doing wrong?

Thanks in advance
Deepak

My mistake jvdeepak, should have recognized the CME in your original posting.  Apologies. Assuming that the call forward all is your VM pilot perhaps.  

Your Cisco CME system by default is set up to allow local transfers between IP phones only. It uses the Cisco-proprietary H.323 call transfer extensions to transfer calls that include an H.323 VoIP participant.

To configure your Cisco CME system to use H.450.2 transfers (this is recommended), set transfer-system full-consult under the telephony-service command mode. You also have to use this configuration for SIP VoIP transfers.

To configure your Cisco CME system to permit transfers to nonlocal destinations (VoIP or PSTN), set the transfer-pattern command under telephony-service. The transfer-pattern command also allows you to specify that specific transfer-to destinations should receive only blind transfers. You also have to use this configuration for SIP VoIP transfers. The transfer-pattern command allows you to restrict trunk-to-trunk transfers to prevent incoming PSTN calls from being transferred back out to the PSTN (employee toll fraud). Trunk-to-trunk transfers are disabled by default, because the default is to allow only local extension-to-extension transfers.
