I have been using Gizmo5 or SipPhone for close to 2 years. My parents have returned back after a 6 month trip to US. Now when we connected PAP2T instrument it is not connecting. We are using Airtel at home. When I tried doing a ping to proxy01.sipphone.com it is printing the ip as 127.0.0.1 (local loop back).
When I called Airtel customer support they stated that all ISP's have blocked this IP. I have asked them to ping and "telnet proxy01.sipphone.com 5060" observed that they are also facing the same problem. But it is working from BSNL. Customer support has requested for the tracert from Airtel and BSNL. I guess they might remove the local loop back or IP blocking. If this is done we can connect again using Gizmo.
This is going to be a long post....Sorry!
Thanks essbee/cyberwiz. Update on my tests. To confirm what vijaishankar was doing, I took my
AC-211-SR voip adapter to my neighbour's place. They use BSNL broadband (vs. Airtel at my place). The moment we plugged the adapter into the network, it registered and the VOIP light was lit and dial tone was there and I was able to make calls.
Now, we came back to my home to implement what cyberwiz was suggesting (port forwarding). Just to be safe, I went to portforward.com and clicked on
Router guides and chose DI-624 (
D-Link) and chose the application as Gizmo Project. I had my DHCP configured in D-LINK such that my VOIP adapter was always getting a static IP of 192.168.0.100
When I put that static IP in portforward.com for DI-624/Gizmo project, it suggested going to Virtual server on my D-link & enabling both (UDP/TCP) for the following 3 ports with ALWAYS set to true: 5004, 5005 and 64064. In addition, I added my own condition for 5060 and 5061. also, please note that my Airtel DSL modem is set up in Bridge modem with the D-LINK wi-fi router establishing the PPPoE connection.
I saved everthing, rebooted my D-link router and then replugged my VOIP adapter into my d-link with the hope that port forwarding will help my adapter establish connection with sipphone. Also, I confirmed that my SIP settings on AC-211-SR were still intact (of course, the fact that it worked with BSNL broadband at my friend's place further confirms that ac-211-sr is fine). NO LUCK. Just as vijayshankar's parents experienced, the VOIP/VOICE light is not lighting up. No dial tone. The only difference is that if I go to my PC (connected to d-link router via LAN) and type ping proxy01.sipphone.com, it comes back with all 4 packets sent, 4 packets received, Lost = 0 (0% loss).
What am I doing wrong? The only that I did not do (that cyberwiz suggested) was to place my router in the DMZ zone. I was thinking that my virtual server/port forwarding settings were enough to get my voip device to register correctly.
I am having a techie friend come early tommorow to play around with my D-link device and my connections some more. Experts, is there anything else that I should do? I am still thinking that Airtel is blocking some port that SIPPHONE.COM uses, but unable to prove it!
Experts, please help me fix this issue.
