SIP conference phone maximum lines stuck at two. Soundpoint IP 7000 with CUCM 7.1

SIP conference phone maximum lines stuck at two. Soundpoint IP 7000 with CUCM (Cisco unified call manager) 7.1

I did some searching but no luck. Sorry in advance if the solution should be overly obvious.

The problem is that I can't add more then two people to a conference call on the fly. I imagine there is some easy change that needs to happen to allow more callers to be added to the phone's on the fly conferencing. In CUCM if I go to the associated line under "Multiple Call/Call Waiting Settings on Device" it says "Note:The range to select the Max Number of calls is: 1-2" If I try and change this value I get error: "Update failed. Sum of device\'s line appearance values for maxNumCalls exceed  device limitation".

How can I fix this?

I tried increasing the related value on the Polycom devices website but no luck. I also reviewed the setup pages in CUCM for "Device configuration", "Button template", "phone profile", and "SIP profile" but did not find where I can set the "maxNumCalls"

Re: SIP conference phone maximum lines stuck at two. Soundpoint

If you're registering this as a 3rd party SIP this is WAD.

Review this:

Migrating from Cisco Unified Communications Manager Release 5.0 to  Release 7.1(2)

In Cisco Unified Communications Manager, Release 5.1(1) and above,  certain characteristics for Basic and Advanced Third-Party phones that  are running SIP changed. These characteristics include changes to the  Maximum Number of Calls per Device, Default Maximum number of calls per  DN, and Default Busy Trigger per DN fields that display on the Directory  Number Configuration window in Cisco Unified Communications Manager  Administration. See Table B-3 and Table B-4 for more information.

Re: SIP conference phone maximum lines stuck at two. Soundpoint

Daniel,

The number of people you can invite to an Ad-Hoc conference is controlled not by any parameter of the phone, but by a CUCM service parameter.

Service Parameters > Call Manager > Maximum Ad-Hoc Conference Participants

I believe the default is 4.

What type of conference bridge are you using in this scenario? IOS HW CFB, or CUCM SW CFB?

If the service parameter checks out then the next thing to check is the number of available resources on the conference bridge you're invoking. The conference bridge invoked can be controlled by changing the MRGL and MRG configuration of the phone hitting the "Conference" softkey.

Re: SIP conference phone maximum lines stuck at two. Soundpoint

Hi Jason;

I have the same problem. I have a CUCM 7, I use the POLYCOM 7000 as THIRD PARTY ADVANCED SIP, the maximum ad-hoc to conference is 16 , as well as other conference itens. A point is that MRG set in this device, to use conference bridge software and hardware together, but is not a problem for other devices in this environment that use SCCP.

What do you think?

Hi Kunle;

My problem was resolved with firmware upgrade in SOUNDPOINT IP 7000 POLYCON. I haven´t version used because this proceeding was done by my customer, but it did that conferences ok now. My suggestion is : upgrade in ip 7000 to the most recent version.
