Analog Conference phone on H.323 Gateway

[coconino1969]

Hello again guys,

I have an analog conference phone using an FXS port on a H.323 gateway, the analog phone is not capable of 3 way calling right now.

Before changing the gateway to MGCP I wanted to ask if its possible to have 3 way calling using an FXS line on an H.323 gateway. The number being used is currently set up as a route pattern in CUCM 7.1.

Hi,

You will need to configure the dial-peer to be controlled by SCCP using stcapp. This allows the port to utilise the DSP chips on the gateway so that you can have 3-way conferencing.

Example config:

stcapp ccm-group 1
stcapp

dial-peer voice 22 pots
description **Dial Peer for Main Conference Phone**
service stcapp
port 2/0/2

Cheers,

Phil

Phil, thanks for the answer. I was unable to start the stcapp service in my gateway.

I'm using a 2821 with IOS 12.4(13r)T running in it. I did get the SCCP service started, but stcapp was not available at the CLI.

What am I doing wrong? IOS perhaps?

Thank you in advance.

For stcapp, you need a minimum of 12.4(15)T
