DSPFARM Conference bridge

Unanswered Question
Dec 21st, 2008

I have created a local conference bridge resource on a 2811, which is registered on our CUCM 6.1:

sccp local FastEthernet0/0

sccp ccm 10.40.122.82 identifier 1

sccp ccm 10.30.8.81 identifier 2

sccp ccm 10.40.123.80 identifier 3

sccp ccm 10.30.9.81 identifier 4

sccp

!

sccp ccm group 10

bind interface FastEthernet0/0

associate ccm 1 priority 1

associate ccm 2 priority 2

associate ccm 3 priority 3

associate ccm 4 priority 4

associate profile 2 register CFB_WA_HER

associate profile 3 register MTP_WA_HER

associate profile 1 register XCODE_WA_HER

!

dspfarm profile 1 transcode

description XCODE_WA_HER

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

maximum sessions 4

associate application SCCP

!

dspfarm profile 2 conference

description CFB_WA_HER

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

codec g729br8

maximum sessions 4

associate application SCCP

I have added these resources to a Media resource group that I have assigned to the device profile that the phones at this particular location use.

Now, when make a call to a phone then hit the Conference soft button, dial the 2nd phone and hit conference again, this is were all phones disconnect as if there is no conference resource available at all.

how can this be diagnosed? How do I check if a conference request actually reaches the gateway, or if the MRGL is exhausted, causing the disconnect?

'show sccp' will show the registration status.

'debug sccp messages' will show communication with CUCM.

For more details, get detailed level callmanager traces. Record the exact time you disconnect and look at the traces around that time.
