Inbound Caller Id from Europe to US

Question
-
An inbound call, from Europe to US through PSTN, goes through my gateway to Lync. The Caller ID number from the PSTN is 33#########. I would like Lync, or the gateway, to normalize that to E.164, but there is nothing from the PSTN to indicate it is an international call. Suggestions?Thursday, June 28, 2012 8:34 PM

Strictly speaking an inbound call for a US number should start with a 1 regardless of what is local and what is not but I know this is rarely the case with lot of telecom providers in the US. As much as a pain as it is you should work through this with your telco provider to make sure they are sending numbers in the correct format.

Does the caller ID of the international call show the country code e.g. 33 for France, 44 for UK? It should.
If so, you could create a rule to prepend a + to these numbers to normalise to E.164.

Hi,
Justin is right. Please check your Gateway has the option to add a + for the incoming number. In fact, incoming call will use the Dial Plan Globle Policy to change its number format(I have tested about it). So you also can create a Normalization Rule to add + for the incoming number.

I know all that. How do I distinguish between a caller ID from the US, which I would add +1 to get E.164, and a call from international, which I would only add + to get E.164?

As a follow-up, my telco said they could not send Callerid for US numbers starting with a 1. That seems pretty lame, but what I expect from a telco.Tuesday, July 3, 2012 8:03 PM
