I believe you can configure your router to be a software MTP with “codec pass-through” as long as you don’t need transcoding. Then you won’t need DSPs.

I'm guessing the only things I would have to do is ensure that I have enough MTP resources on the trusted device. I could use the DSP calculator for that. --- Lelio Fulgenzi, B.A. Senior Analyst, Network Infrastructure Computing and Communications Services (CCS) University of Guelph 519‐824‐4120 Ext 56354 [email protected]<mailto:[email protected]> www.uoguelph.ca/ccs<http://www.uoguelph.ca/ccs> Room 037, Animal Science and Nutrition Building Guelph, Ontario, N1G 2W1 ________________________________ From: "Brian Meade" <[email protected]<mailto:[email protected]>> To: "Lelio Fulgenzi" <[email protected]<mailto:[email protected]>> Cc: "Cisco VOIP" <[email protected]<mailto:[email protected]>> Sent: Tuesday, February 17, 2015 11:34:22 AM Subject: Re: [cisco-voip] trusted relay points They're basically just MTPs you deem to be "trusted". A lot of people use them for switching between IPv4 and IPv6. Really not anything different than just forcing MTP Required other than maybe just narrowing down the MTP list. Some people use the same setup for VPN phones/IP Communicators over VPN so VPN clients don't have to be able to talk directly to each other.

There's not much on the subject in the guides, other than saying some MTPs are trusted relay points. Our thought was, rather than opening up the voice VLANs to allow media from the data VLANs, we could simply set up the Jabber clients with "trusted relay points" enabled and modify the voice VLAN ACLs to allow access from these trusted relay points. We could either use our PSTN gateways or deploy another set of 2900s for this purpose. This would also help us in the short term, I believe, by not having to enable "peer to peer" communications on our wiLAN. Any thoughts or pointers to some documents would be fantastic.
