Sending calls with witheld numbers into Exchange 2010 UM

[Richard May]

Hi,

 

I have integrated my SnomOne with Exchange 2010 UM.

 

As long as the incoming call has a CLI number available, it is correctly routed to the Exchange 2010 UM to record a voicemail.

 

If the number is witheld, the voicemail reverts to SnomOne voicemail.

 

Does anyone know how to fix this?

 

Thanks,

You mean the "From" header shows "anonymous"? Where does the call come from? From an extension or from a trunk?

From a trunk (either PSTN or SIP) where the incoming caller has witheld their number.

I dont see what that would keep the PBX from sending the call to Exchange. Can you check if the PBX tries to send the call to Exchange (SIP messages between the PBX and Exchange)?

Yes, it tries and fails.

 

There was an error in my original post, the problem only relates to calls (with withheld numbers) that are routed in from my SIP provider (VoIPTalk) calls from PSTN (via a Patton gateway) work fine even if from withheld numbers.

Okay, getting closer... I suspect that Exchange has a problem matching the request to something valid. Maybe this is something that can be setup on the Exchange. If the To-headers are the same, IMHO that should be possible. I am not a big Exchange expert, maybe someone else can help out here.
