Steven--<div><br></div><div>at my former job, we did implement VRF for the voice network. I don't know about now, but at the time H323 was the only supported VRF VGW. Now if you could put a VGW behind a VRF with out having to setup VRF on the Router you could still use VRF with MGCP. Works pretty slick over ethernet connections. Not so good over T1's. We had to setup GRE tunnels to get the VRF Voice back into the normal VRF instance.</div>
<div><br></div><div>everything came back to our FWSM, but I hear that is changing to ASA, so all the Voice was statefully firewalled.</div><div><br></div><div>YMMV</div><div><br></div><div>Scott<br><br><div class="gmail_quote">

<div>There was a good thread a couple of years ago regarding the use of VRF and VOIP. </div>
<div> </div>
<div><a href="http://www.gossamer-threads.com/lists/cisco/voip/104942" target="_blank">http://www.gossamer-threads.com/lists/cisco/voip/104942</a></div>
<div> </div>
<div>At that time it was indicated that the best practice is to use the global routing table for VOIP though 12.4.22T added some limited support for H323 and SIP.</div>
<div> </div>
<div>Wondering if it would now be possible to support remote Call Manager sites on VRF. I have a situation where it would be advantageous to have phones and trunking on Call Manager Cluster A on one VRF and phones and trunking on Call Manager Cluster B on the global. These sites are a mixed bag of MGCP and H323, on 29xx routers with SRST and the Call Manager cluster are both 7.1.3. </div>
<div> </div>
<div> Due to the various components that would have to be dealt with such as SCCP resources, dialpeers and SRST I doubt this would work but I thought I would check. Maybe there is some new magic out there.</div>
<div> </div>
<div>Thanks for any feedback!</div>
