HW conference bridge

Hello folks

I'm trying to configure a 2811 to run as a hw conference bridge

I have 2 PRIs up and running on this GW, I have a PVDM2-64,

however when I'm configuring the dspfarm profile when I try to issue the maximum sessions command the only option is 0, could you point me on the right way to solve this issue

thank you

Re: HW conference bridge

Indeed you need more resources, what is the output of a 'show voice dsp' and also froma 'show dspfarm all'

Re: HW conference bridge

AFAIK 1 DSP = 4 channels

If you are using a T1 then is 24 channels hence you need 6 DSP's

and from this link:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/5x/50media.html

The PVDM2-64 only has 4 DSP's

If you remove the T1 are you allowed to add the HW Conference Bridge?

Re: HW conference bridge

I haven't tried that yet. but i'm pretty sure that if I remove one i will get 4 dsp channels

Re: HW conference bridge

actually a DSP means 16 channels, that's why the PVDM2-64 has 4 DSPs. a PVDM2-8 is only half DSP, 8 channels.

you have 2 T1/E1 on that card and a 4FXO card

most probably you're not leaving the whole DSP that is required to configure CFB, meaning 16 channels. a sh voice dsp and a sh run can confirm this.

if you're using both T1s + 4fxo those are 52 channels out of 64, meaning you don't have enough resources. if using both E1s and no FXOs then that leaves even less resources free
