We have a customer that is using Bell's Sympatico "Unplugged". I can tell you that as of today, Bell is blocking all SIP/SDP messages so standard VoIP doesn't work. The SIP phones/ATAs register correctly, but the INVITE messages (inbound and outbound) are blocked. There are some reports on the net that Vonage is working but I don't know for sure. There are also reports that Rogers is doing the same thing.
To get around the issue, we setup a FreeBSD box at the customer site as their router, and then setup a PPTP tunnel from the FreeBSD router back to Cisco router on our network. All network traffic is then routed over the tunnel. This way, all that Sympatico "Unplugged" sees is PPTP tunnel traffic. This works like a charm. Assumedly you could do this with any router that has an embedded PPTP client instead of a FreeBSD box. We tried with some Linksys routers that were flashed to OpenWRT or DD-WRT, but we didn't have much luck. The clients on those platforms were flaky. We would have just used a GRE or IPSEC tunnel, however we found both of those tricky to setup in an environment that had dynamic IP addresses (Sympatico "unplugged" uses DHCP) Regards, Bill ----- Original Message ----- From: Chuck Mariotti To: [email protected] Sent: Monday, March 19, 2007 4:34 PM Subject: [on-asterisk] VoIP/SIP on Roger's Portable Internet Is anyone using Roger's Portable Internet with SIP clients to Asterisk? I want to know if it works before I waste much time on it (too much latency, etc.) Regards, Chuck
