Dear All, One of my Friend setup an Asterisk Box as SS7 Termination Gateway.From my netflow report, I can see only UDP packets in this gateway. No TCP 1720 or 5060 connection. Network diagram is: Remote VoIPSwitch>>> Asterisk Termination Gateway for SS7>>> Telco SS7 Link Now my question is. How it works without any TCP connection!!! I'll be grateful if anyone tells me the hidden technique beside this technology. Thanks, Sumon -------------- next part -------------- An HTML attachment was scrubbed...
