Central DSP configuration for remote sites

Is it possible to configure remote ip-phones to have resources from a central DSP farm from the CUCM 6.0?

I have remote sites with ip-phones, but only 4 DSP farms at 4 central sites (Cisco3845 full of PVDM2-64 cards, can the remote ip-phones get DSP resources from the Central-Sites DSP farms?

I'm using CUCM 6.0.

Re: Central DSP configuration for remote sites

Is it possible-Yes, but it is not recommended. Usually solutions are desiged around hardware DSP resource at the remote sites and software resources at the Main site. Here is media resources chapter from Cisco SRND.

Re: Central DSP configuration for remote sites

Thanks. I already read the chapter, so, its is possible but not recommended.

Any configuration guide to do this kind of deployment using CUCM 6.0? (centralized DSP farms and remote phones)

Re: Central DSP configuration for remote sites

If you configure the DSP farm as you normally would and register it as a transcoder. That will be assigned to a media resource group (MRG) and that assigned to all the phones. Not sure if this is what you mean but that would mean all the phones use all the same resources.

I think the reason DSPFarms arent recommended is because the call will Unnecessary cross the wan.

Yep i agree with Matt, here is a guide on registereing a DSP farm with CM. Guide discusses about 4.X, but it can be extended to 6.X

I think that guide may be a bit out of date probably check this one out if your using NM-HDV2 or PVDM2 DSPs.
