Probably not supported but I think it should work. 2 sites each with a Zen ADSL connection. IP 406 at site A and 401 dt4 at site B each with vcm 5 fitted. Can set up calls 50% of times, run call status at each site and shows a connected call but no speech path! using cisco routers at each site...any help much appreciated

We are experiencing a similar problem (although 70% success rate, 30% drop out) with a VPN IP PM Pro from DSL into our network (2Meg Lease Line).
What did you find with ARP / Proxy settings? It may serve as a pointer to isolate the problem for us.
Thanks

This is probably issues with your firewall settings on the cisco or a problem with your ISP
once a Voip call has been setup the systems use ports $C000-CFFF for actual Voice trafic, these ports need to be passed thgrough to the IPO by the cisco.
it is also worth noting that "some" isp's use some of these ports within thier network & may not be available for use
