Call forward external with no ring-back

Hi all, on my CCM 8.6.2 when a user set the CFA on external number (ex. mobile phone) who call the extension from outside don't hear the ring-back.

Ring-back: internal DN -> internal DN (with external CFA)

No ring-back: outside caller -> voicegateway -> internal DN (with external CFA)

on answer all is working and I can hear both voice.

The gateway is H323 (2921), and the call coming in by E1 line and come out with the same E1 controller.

this is my conf:

!

dial-peer voice 10 pots

translation-profile incoming zero

service num2name

translate-outgoing calling 3

translate-outgoing called 3

incoming called-number .T

fax rate disable

supplementary-service pass-through

direct-inward-dial

!

dial-peer voice 33 voip

destination-pattern 1234567..

translate-outgoing called 3

session target ipv4:192.168.55.1

dtmf-relay rtp-nte cisco-rtp h245-alphanumeric

codec g711alaw

!

dial-peer voice 32 pots

destination-pattern 0T

port 0/1/0:15

!

Incoming dial-peer (from outside): 10

dial-peer to CM(8.6): 33

dial-peer to outside (to reach extenal number): 32

On the Call Manager (192.168.55.1) I have a DN with CFA to external number

Any suggestion?

These have nothing to do with your problem. Check following document:

Call forward external with no ring-back

The strange things is that it works with every number except one that the customer need!! If I call directly I hear the ringback but not when I forward a call to it.

I my debug I see:

Call forward external with no ring-back

You should see that with other numbers, alerting is received on the outbound call, and that causes the tone to be heard.

Can you try 'voice call send-alert'.

New Member

Call forward external with no ring-back

I found that the number where I forward the call to is a voip account forwarded to a mobile number.

So:

My PRI -> My internal phone (with CFA) -> extenal VOIP account (through same PRI) (with CFA on mobile) -> mobile phone

So the situation is a bit strange (two nested CFA ), if I remove the last forward on mobile all works.

Maybe isn't a problem on the Cisco side....
