Call forward all issue

Unanswered Question
Oct 12th, 2008


We are using CUCM 6 in our production network, we have an issue with call forward.

When a DN is forwarded to a mobile number, the calling party doesn't hear any ring back but the mobile rings and the calling party will get connected as per normal when the call is answered. But when the call is answered, the ANI shows the preceding digits as internal and the last four digits as the last four digits of the mobile number.

I believe it should be a global setting, any solutions?


I have this problem too.

Thanks for the reply, please note that under normal circumstances when a call is made from the IP Phone it connects ok and the user can hear ring back. This issue is only present when the call is forwarded to Mobile or other external numbers. I believe in this case the call is made from the call manager and is routed through a h323 gateway VOIP provider. There is no other gateway involved here.

Any other suggestion? the other issue is when the call is forwarded the ANI also shows the wrong number, it show the first four digits as the internal number and the last four as the last four digits of the mobile number.

Hi, Under the H323 GW configuration on the CUCM enable "Enable Outbound Faststart" and it will fix it.

on the out going pots dial-peer

tone ringback alert-no-PI

progress_ind setup enable 3

progress_ind alert enable 8

progress_ind progress enable 8

progress_ind connect enable 8

these commands on the global config

voice call send-alert

voice rtp send-recv

make sure that you reset your gw
