Hello Prashant,

We are facing issue for outgoing ISD calls only other outgoing local & National calls are working fine  ...able to receive all calls no issue for incoming calls...

We are having CUCM 11.5 & VGW ...SIP Trunk is created in between ...

I am attaching Debug & sh run configuration...when we dial ISD number we are getting reng back tone after 7-8 ringback tone call cuts ...even we dial the International IVR number where e are hear ring back tone & not IVR prompt

Hi Vijay,

In your GW debug i see there are 4 outgoing calls to your ISP, can you confirm which call we are having issue with 3rd or 4th. They all have their own and different disconnect cause codes.

If this is the correct Number then make sure you are sending it it correct format as expected by the ISP. The Provider is rejecting the call so you need to check with them on what format is expected for international calls.

I see that calls are getting rejected due to Unallocated/unassigned number which may indicated wrong number being dialed and Normal Call Clearing.

Thanks
