setting up hardware conferencing with CM4

I have a 7936 phone and I am attempting to setup a hardware conference bridge for our phone. I want to have it use a hardware bridge so we can add several people to it at once.

I dont think I have it working correctly. I cannot get more than one person conferenced in. When we attept to call someone the following happens.

1-- call placed to external phone. We press conference and then attempt to dial antoher external number. Once we have that, we hit conference again and it does not join the two calls.

CCM 4.1

I have the following config

Am I doing something wrong here?

When I do a sh telephony-servi con I get nothing, Am I going to have something there?

Re: setting up hardware conferencing with CM4

You mention CCM 4.1, but your config appears that you are trying to register the conference bridge locally to an instance of Callmanager Express. If you want to register the bridge to CCM, the "sccp ccm 10.X.X.2 identifier 1 version 4.0" command should point to your Callmanager, not the local box. Also, in this case the "telephony-service" commands are not necessary.

Hope this helps.

Re: setting up hardware conferencing with CM4

No I am using CME 4.1 . I changed the config to sccp ccm 10.X.X.2 identifier 1 version 4.1

Re: setting up hardware conferencing with CM4

Does 10.x.x.2 match the address configured for the "ip source-address" command under telephony-service?

Re: setting up hardware conferencing with CM4

Since I corrected the .40 to 4.1 and added the ephone I can not conference a total of 4 people.

1 internal call (the conf creator) and 3 external callers. When we attempt to do the 4th one it goes fast busy.

Am i missing something else now?
