Using Diversion in SIP trunking

[miteltechswe]

Hi Guys,

I apologize if this question is already somewhere on this board, i looked around but couldn't find any relevant answers.

At the moment i'm working on getting external CLID to work on dynamic extensions over SIP trunks.
The service provider does support this but need the Diversion header in the invite to identify the correct source of the call.

I've tried setting "Public calling party number passthrough" to yes but this only seem to change the from header to the calling party ID which is sort of correct, however i would need the Diversion header added as well so that the call can be authorized to the PSTN.
Is there any way to get the diversion header added from the mitel controller or do i need to do manipulate the headers in an 3rd party device for example an Ingate sip module?

I only need to know if we can add diversion headers and if so how to do it, the rest i can probably figure out by myself.

thanks in advance.

It works just fine for me and has for the longest time. I will look at my settings tomorrow.

Is ANI Okay goings out for a regular set call?
