- AIRTEL DSL 512kbps
Hi all:Finally, a post to say that my AC-211-SR VOIP router registers with SIP phone again and everything is fine.After making all kinds of changes (suggested by Cyberwiz/essbebe), I was about to give up. Then, to compare my tracert with what Cyberwiz was getting, I went co command line and typed:tracert proxy01.sippphone.comI did not mention any port(like 5060) as that seemed to time out after 30 tries. It finally came back around 400 ms (almost 1/2 a second) and it was a lot slower than what cyberwiz posted and slower than what I used to get (on ping - around 100ms).With this information, I accessed the only page on my AC-211-SR that I had not checked before, viz. SIP->SIP EXTENSIONS. There, I believe that the values for SIP session timer value and SIP registration timer value were blank. I changed those 2 values to 60 (secs).I then reset my router (re-booted my VOIP router) and voila, it came back with the VOIP/Voice light lit-up. I got a dial tone too! Made a few test calls and everything works fine for now. It's been 3-4 hours since I made the change and everything works for now.The only bit of education that I might have gotten out of all this mess is that:maybe, around the time of the Airtel undersea cable fault late 2008, the # of hops (as shown by tracert) from airtel to sipphone.com increased significantly (mine now uses at least 20 before registering with proxy01.sipphone.com), causing some hardware adapters with insufficient SIP registration timers to no longer register correctly.I wonder if vvijayshankar is experiencing the same issue (also using gizmo project ata, except using a Linksys device instead of ac-211).Thank you all (espl. cyberwiz and essbebe for helping out a lot!). Now, I am back to the phone again (to talk, rather than poke around settings).
