I also ran into a solution from Barix. &nbsp;They have firmware that can be added to their Barionet 100 Router that turns it into a Multicast Tunnel.

We're using Astra Phones and have set them to do group paging. &nbsp; There are two groups of phones on two different subnets. &nbsp;Unfortunately the subnets are not in close proximity to each other so we have to link them over a VPN between our two Edgemarc 4550 routers. &nbsp;We've programmed paging so group one responds &nbsp;to paging when it sees packets addressed to 224.0.0.100. &nbsp;Group two responds to paging when it sees packets addressed to 224.0.0.101. &nbsp;All phones respond when they say a packet going to 224.0.0.1.<br />
<br />
Things work fine when everyone's on the same subnet. &nbsp; When we split them up and rely on an Edgemarc VPN we can't page the remote subnet since multicast packets aren't routed.<br />
<br />
Is there any commercial solution that we can use to get around this situation? &nbsp;I have yet to find a device that will encapsulate multicast packets for rebroadcast on remote segments. &nbsp; I thought that maybe cyberdata might have an appropriate solution. &nbsp;They seem to have a sip paging system but I don't know if it will put out multicast packets.<br />

How can I solve this problem?

VOIP Multicast Paging Solution

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.
