Hi marwanshawi,

I have tried to add MCU as a conference bridge in CUCM, its registed successfully. Do you know how it wiil work in this case?

Thanks

[Marwan ALshawi]

Ok add it to a media resource group

And MRGL

THEN assigne it to the desired phone and trynto make an adhoc conference using this mcu hardware conf resource

HTH

Sorry from late response, I want to use it as incoming conference bridge with a password authentication.

thanks.

I think if you register it you can not have this ability

However if you integrate it with CUCM via sip trunk or h323

Then you can pre define conferences with password and number to be dialed from CUCM using a route pattern over the trunk you add that points to the MCU

Hope this help

thanks, its working very well.

The only issue i am facing is that only two participant can dail-in, if i try third one it gives busy tone.

[Marwan ALshawi]

Do you have enough ports in the mcu ?

[amrishmehta]

yes, I have 6 HD and 6 audio ports

[Marwan ALshawi]

Check the conference and default conference settings and see if there is any limit

It shouldn't be an issue since you are able to join it !!

[amrishmehta]

There is no other setting for this. Same problem i have with EX90 when i registered it as a third party sip device. it does not take fourth participant in conference.

[Marwan ALshawi]

Ex90 is different you have to enable multisite calls

And intiate the call from the ex90

And max of three participants only
