I’m facing a problem for users under 3G, where several 3G carriers are manipulating udp service, so there’s no way to get user available under 3G using UDP. I was turning and testing all option, the unique way to get the sip user reacheable was turning to tcp, which is not the best option.
I have tested to use an external proxi service like pproxy.net, and it seem to be true, using a proxi router before my asterisk, it allow users to connect under 3G and being available without any problem.
So, I wanted to setup a Proxi server, into my own switch, or in a small external server to do traffic routing in front of my asterisk.
I was checking around, and I haven’t found other option then Siproxd, or I don’t know if someone else have another experience with other server, or other solution, for high avaiolability proxy server t un with asterisk?
Thanks for sharing, or advicing,
