Busy tone

[amarni333]

Hi,

We are experiencing a very strange issue, some of our DID numbers(e.x 408-702-1113) are encountering busy tone all the time, but some are working well. We have contacted our local telecom vendor and they said it could be our internal issue. So my problem is, how could we do self check the PBX where the issue is, we are really need you guys help... any suggestion is appreciated.

Best Regards,

Are you using DDi translation on the Trunk Group??

Hi oldboy,

I am sorry, could you please tell me where I can check this?

Go to Trunk Groups, open the one you are using and see if DDI Transcoding is ticked. If it is you need to go to Translator/external Numbering plan/DDI Numbering Translator and see if any entries are there..
