OXO Connect - Issues with DLT2

[Smith988]

Good morning,

Due to developments, an OXO Connect IPBX was installed at my workplace.

I have already worked with Alcatels, but that is remote from the OmniPCX 4400, so nothing to do with this model.

I have successfully configured my DLT2 link with the remote autocom and can make calls within the company dial plan, but I cannot reach outside!

I absolutely have to go through the master autocom which is a MITEL and when I use my main trunk the calls starting with "0" or "00" are all rejected.
I don't understand why and I don't know where to look...

Have you ever had this type of problem? If so, would you be able to help me because this is really detrimental to my subscribers.

Thank you in advance for your help and understanding.

Sincerely,
John
