Cisco ATA186 & call manager config question?

Unanswered Question
Jun 28th, 2009

Hi There,

I hope I can get some assistance with a configuration issue that I'm facing when setting up a lab environment using a phone line, an ATA 186 and Call manager. I'm connecting a phone line (PSTN), to the ATA, which is connected to the same LAN as the call manager. It is configured to get an IP address by DHCP. This works fine as I can see the ATA registered in call manager with a valid IP address. The problem I'm facing is that as i'm not using a gateway and I'm not sure whether I can route calls via the ATA. As far as i understand only a gateway can be assigned to a route group, to be assigned to a route list and subsequently to a route pattern. So my question is whether I can somehow connect the phone line to the ATA, and configure it in call manager in such a way that I can receive and make calls via the number allocated to that phone line connected to the ATA without the need of a gateway?

I'll appreciate any input on this?

Kind Regards,

Esteban

I have this problem too.

ATA has FXS ports not FXO ports

you cannot use ATA for routing calls to PSTN

You need Cisco IOS GW or other GW, not ATA

Thanks. I have now a VIC card available, the VIC-2DID and a 2600 series router (2611). I've read that this card has dual working modes, FXS and DID. Do you know if the DID mode is equivalent to FXO? If yes can this VIC card be used in the 2611 router with a suitable IOS?

Esteban

Hi Rob,

Since i need to connect a card directly to a standard Telco line, so i should be using an FXO voice interface card. I'm trying to get one. Do you know if the VIC2-2FXO will work on a cisco 2611? I can't seem to find a VIC-2FXO.

Best Regards,

Esteban
