VG200 FXO-M2 ports and caller ID

--begin ciscomoderator note-- The following post has been edited to remove potentially confidential information. Please refrain from posting confidential information on the site to reduce security risks to your network. -- end ciscomoderator note --

VG200, 2 VIC-2FXO-M2 cards, four ports total, all MGCP gateways on CCM 3.1.3(a). Have two straight POTS lines hooked into both ports on the VIC (I'm testing right now).

I have enabled caller ID on all of my FXO ports, but calls from the PSTN through the VG200 still show up as "External Call (Unknown Number)" on our IP phones. Yes, the lines are enabled for caller ID from the PSTN as well; that's why I'm puzzled as to why this isn't working. This is the first time I've set one of these up, so if there is an obvious solution, I apologize in advance. Any suggestions would be appreciated. My sh ccm, mgcp, and voice ports are below.

Re: VG200 FXO-M2 ports and caller ID


Internally found moderate defect: Duplicate (D)

Voice over IP, Caller ID receive failed on M2

Also I found

Incoming Caller ID on FXO with MGCP is not supported by CM AFAIK. The GW gets it (and supports it for H.323) but CM does not get it or does not

interpret it. CM supports Caller ID only outgoing on FXS with MGCP.

You may want to double check on this .

Thanks for the response - that's what I was afraid of. I'll have to give H.323 a try.
