Inbound Call UCCX Transfer to PSTN

Hi All,

 

I have issue with UCCX to transfer call, what simulation has been done are :

1. Calling from internal to external number (phone number) via UCCX , result is success

2. Calling from external (phone number) to external number (phone number) via UCCX, result is fail

 

UCCX version : 

8.5.1.11004-25

 

CUCM version :

8.5.1.13900-5

 

Here is log that i gather

Any advice for this problem?

Re: Inbound Call UCCX Transfer to PSTN

This isn't enough information to troubleshoot the problem. The last three characters of the callref in your debug isdn q931 output should all match for the same call leg. Since we cannot see the callref for the SETUP message, we don't know which subsequent messages are related.

Also, the fact that you can even hit the gateway tells me this isn't an Allow Off Net to Off Net transfer restriction in CUCM, nor does it seem like a CSS Class of Control issue either. If those Cause values you've hightlighted are related, then it seems like the number format is wrong, in which case you would either need to:

a) correct the number format
b) turn on RDNIS
c) ask the carrier for unscreened ANI service

Can you capture a complete debug for us, and then also, can you capture the working debug too for comparison?

Lastly, can you even call forward a phone to an external number and call that phone from an external number (off net to off net call forwarding)? It should work somewhat similar to UCCX doing it. You might find the problem is not with UCCX at all.

Re: Inbound Call UCCX Transfer to PSTN

Hi Anthony,

 

Thx for Answer, this issue has solved

 

Somehow carrier see the format we gave is wrong, maybe there r some changes in carrier

 

So we add masking in the router(translation pattern), after that, it solved
