Hi Nasir,

Do you want to use the basic adhoc conference feature?

If yes, enable IP Voice Media Streaming App Service on the CM servers. This will host CUCM's' software conference bridges that will registered with the call manager.

Add them to the MRGL of the phone trying to conference and the basic adhoc conference would work for G711 only.

Please elaborate if you have some other requirement.

Regards,

Dear, By default conference works for internal phones if "IP Voice Media Streaming App Service" is activated on CUCM, nothing needs to configure for it.

How to make conference call; you can check video clip on youtube.

For meet me conference; you need to configure meet-me number in cucm and then you can use for conference.

If you want to have conference with external users (PSTN) then you need to configure DSPfarm at cisco voice router (there should be enough free DSPs) and these dspfarm should be registered on cucm.

You can have conferences with

You can have conferences with external parties using the SW CFB, there's no need for a HW CFB bridge. You only need a HW CFB when you want to mix codecs.

Nasir, have you actually tried to make a conference?????

As they guys have mentioned, this is enabled by default, the only config you need (and it's not mandatory) is to get the MRG, MRGL and then assign it to the device pool, or device. And even without MRG and MRGL, it should work.

Hi Java,Yep, I should have

dear expert;

i checked internal conference call option is appearing but when i confirm conference call its disconnected.

service is running and i didn't make any changes.... do you have any document where i can follow the steps for configuration or can you write the steps in point...

if any configuration required on voice gateway also please let me know...

please i need help...

OK, SW CFB ONLY support G711

Jaime Valencia — Wed, 23 Jul 2014 13:25:40 GMT

OK, SW CFB ONLY support G711/G722, if you're using other codec, then either you change it to any of those two, or you will need a HW FCB.

It sounds like you're not using G711/G722, and that's causing the issue, check that.

No, no guides with all the steps.

I cannot tell you if you might need to change something in your VGW, I have no idea of your configuration.

THANKS FOR REPLY.... HOW I

muhammad siddiqui — Wed, 23 Jul 2014 19:14:39 GMT

THANKS FOR REPLY.... HOW I CAN CHECK WHICH CODEC WE R USING... I THINK SO ON VOICE GATEWAY WE ARE USING G711....

When you setup a call, then

When you setup a call, then just press '?' button twice on IP Phone, you will get to know on what codec call has established.
