Analog to IP Phone calls

have anyone done this? making calls between an analog phone and an IP phone?

                                    PSTN
                                         \                     
AnalogPhone----FXSPort-H323GwA--Network--H323GwB--CallManager
                                    \
                              IP Phone

I already set the dial peers on both gateways, setting the dial-peers is actually straightforward, but I dont know whether something is needed to be done inside call manager. Actually I have made calls to the PSTN from the analog phone, but so far I have not been able to call the IP phone by dialing its extension number.

I have no gatekeepers

any config suggestions?

What version of callmanager are you using?

Cucumber

cisco unified callmanager 4.2

Cucumber

I solved the problem, I added the following to the gateway on the call leg to the call manager

voice service voip
allow-connections h323 to h323
redirect ip2ip

Cucumber

Its me again

I found an easier way to accomplish this thing.

1. Inside callmanager, device->Add gateway->H323 Gateway->Specify IP Address of gateway
where the analog phone is pluged in

2. Then, again, in callmanager, add a route pattern, having the extension of the analog phone point to the new gateway added in step one

This saves the typing of many dial peers.

I was going to ask you about that, but wasn't to sure about the fsx ports. In my callmangers that is how we do it. Confing the h232 gateway in the callmanager to send the calls out that way. There is a VG248 in there and not just analog phone on fsx. We use the callmanager just as a way to add voip subscribers onto our pbx backbone, so all the calls are sent via the pbx over T1 lines.

Indeed the callmanager way is the right way to do it.

BTW, I will get to play with a VG224 later on, but I think I will set it up as an MGCP gateway just for testing!

The VGs are pretty simple to set up. I would definatley suggest playing around with it if you have the chance.
