3825 for conference with other site

Currently have a 3825 Voice Bundled router, combined with two UC520 in two remote sites.

Right now we have successfully configured for dialing between these three sites.

But it seems we cannot make conference between user in HQ (3825) with user in other sites (under UC520).

The display keep displaying

"Could not complete conf.."

What did i need to configure on the HQ site.

I've read about configuring call-me and adhoc conference but it seems only for UC, CCM or higher version of CME.

From what i've seen on the 3825 when i perform "show telephony" the CME version is only 3.3

Is there someway to upgrade the CME running on the 3825 router ?

I've tried to upgrade the IOS to the latest version (12.4.21) but it seems the IOS doesn't have to do with CME.

Thank you very much for all comments.

Re: 3825 for conference with other site

i cant see ant dsp conf configured!!

first u have PVDM2-64 in ur mainboard insstalled

which contain 4 DSPs fist one used by the FXS model in ur slot 1 and slot 3

so u can use the other three

each confrence need one DSP

and each DSP support foe Xcoding

so try the following config

sccp local [source interface]

sccp ccm l [source int IP] identifier 1 version [ur cme V.]

sccp

!

sccp ccm group 1

associate ccm 1 priority 1

associate profile 1 register mtp001c58551650

associate profile 2 register confdsp1

!

dspfarm profile 1 transcode

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729br8

codec g729r8

maximum sessions 2

associate application SCCP

!

dspfarm profile 2 conference

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

codec g729br8

maximum sessions 2

associate application SCCP

telephony-service

sdspfarm units 5

sdspfarm transcode sessions 2

sdspfarm tag 1 mtp001c58551650

sdspfarm tag 2 confdsp1

the name must be exactly on the telephony service aND DSP FARM like (confdsp1)

good luck
