how to set the conference participant number in MPX2 used as CFB in CUCM 6

Hi all,

I have configured MPX as a conference bridge in CUCM6.0 here is the config :

Total System Resource Units (SRUs) 375

Remaining SRUs for video 229

Audio licensed ports 32

Audio available ports 32

G.711 ports 10

G.729a ports 22

Audio floater ports 32

Audio overbook ports 32

Video licensed ports 6

Video floater ports 6

Video overbook ports 6

Web licensed ports 13

Web floater ports 6

Web overbook ports 6

Maximum ports per meeting for reservationless meetings 32

Maximum ports per meeting for scheduled meetings 32

Default number of ports per meeting 32

Default length of meeting (minutes) 60

Maximum meeting length (minutes) 240

Meeting ID start guard time (minutes) 30

Meeting ID end guard time (minutes) 30

Extend meeting (minutes) Yes 15

Early meeting start (minutes) 10

Last warning time 2

Minimum meeting password length 0

Maximum advance days to schedule 300

Days until meeting recordings purged 7

Days until meeting statistics purged 120

Allow vanity meeting IDs true

Minimum meeting ID length 4

Enable reservationless Yes

Reservationless: Allow 3rd party initiate Yes

Reservationless: Bill 3rd-party initiator Yes

Host all meetings on external server No

However I cannot exceed 6 particpants in a ahdoc conference, although I have 32 usable ports ( 10 in G711 and 22 in G729).

How could resolve this ? any suggestions ?

Also, is there a tool that allow me to monitor the usage of ports in real time?

thanks inadvance.

best regards,

Re: how to set the conference participant number in MPX2 used as

you need to change the service parameter for max ad hoc conf participants i UCM, by default it is set to 6. just change it to a higher value and you will be fine. However I am not sure that using MPX as the conf bridge is the most value for money in your situation for ad hoc conferences, it is better to use simple DSP resources in a ISR or similar

first thak you for your response.

then, actually, the default value fur CUCM is 4. and I have already changed to 32.

32 participant in a conf is not possible with simple DSP unless we have 6500 switchs.

So, the prob is still there !
