Hi there
Is there anyone that use AMPRNET for connecting VOIP gear (such as echolink alients (or even Digital repeaters (DMR D-STAR etc) and can tell how is the fact that every packet goes back and forth to UCSD router effect the connections ? is the latency not making any problem ?
any comments from anyone that has tried that is appreciated
Thanks Forward

Amprnet is used for VOIP extensively on Hamwan type segments where there is plenty of bandwidth and BGP advertised direct routing on the Internet (no passage through UCSD).
I would be very suspect of good performance through UCSD gateway for both latency and more importantly for voice, jitter. On May 29, 2016 2:33 AM, "R P" ronenp@hotmail.com wrote:

I suspect it wouldn't work very well. The gateway at UCSD is not a high-bandwidth connection. - Brian

I've tried it before and I concur, it's not the greatest way to pass VoIP (via amprgate). You'll find that your jitter will be too great for your application to maintain a good link.
We have use in Europe many Asterisk PBX connected via Hamnet/Amprnet gateways with software phones (like phoner) or hardware phones (like Cisco 7940G) and working very well with connections across gateways.
You can see maps where visible online links between PBX in Europe:

Only 44<->44 network we use for VoIP.
PPX asterisk use DUNDI protocol for this reason if I know phone number which base on callsign:

I have run Asterisk PBX for about 10 years, I have a pretty good idea how it works.
The question is, are you only connecting endpoints that are using the Net-44 addresses or are you going through amprhost (UCSD) out to IP addresses on the general Internet?
If you are using Net-44 only addresses and tunneling then you might get decent latency and jitter numbers -- I suspect not if it must pass through amprhost to and from some address outside of Net-44.

John,
The system runs on 44-net addresses only. German stations are linked by high speed wireless, independent from the Internet. Outsiders, like Waldek and myself use dedicated p2p links to that network. So it has actually nothing to do with the UCSD gateway or the generic tunneling system (but it works via the IPIP tunnels, too).

OK -- I suspect that works fine, but the original poster was asking about VOIP through UCSD amprhost.

I test Echolink and there is little cuts but it works.
Best regards, Ludovic - F5PBG.
I use the bgp method and link our dstar repeaters with no loss or latency detected

The basic idea would be that AMPR to AMPR traffic is a go since it is tunneled directly. Public IP to AMPR is a no-go for tunneled networks. They have a public Gateway IP anyway, so you should use that one for access from the internet.
