How to bypass my ISP ban for VOIP calls in my country?

[hamanky]

I am using VOIP Linksys router in UAE and my ISP has probably banned the service and I think has configured its firewall to block port 5060-5063 or I do not know what other way to manage blocking the service .
It looks like I can’t make VOIP phone calls from their using my Linksys router and my Canadian established phone number .
Any ideas for work around this dilemma?

I had a similar issue in India with the ISP. Despite so many requests, they didn't let me pass through UDP 5060. I learnt that it's common for most of the VoIP providers to be using UDP ports in the 500X and 600X range. I changed my UDP to 10001...booom..it works. See if helps..

I am in the UAE.
I set up my SPA 3102, and it is not registering (failed). The SPA does not receive any SIP messages. I tried the suggestions above but no luck. I tried, and had the same with a Grandstream BT-X. I took the Granstream to the US and it worked perfect. I contacted my SIP provider and they informed me that they are receiving the SIP messages from my SPA and where sending replies.

The strange thing is that only my Siemens IP phone seems to work on the UAE-Etisalat ISP. Why does that work and the others don’t?

Has anyone had luck configuring the SPA to work in the UAE?

hi Sam, can you tell me how your Siemens IP phone worked and where did you get it from. I will use this option if it will work.

The UAE actively blocks VOIP calls. I believe it does more than just port-blocking, and uses deep packet inspection to identify and block VOIP calls.
You could try using a provider that allows you to connect on Port 80 (rather than 5060) or use your existing provider but route it through a virtual pbx like www.pbxes.org which does allow connections on Port 80.
Saying that, it may still not work, the UAE blocking is quite heavy.

1) I tried the above, no luck.

2) I really dont know how my Siemens phone works. If I knew, I would be able to get the other devices to work as well.

The issue is in receiving the packets and not sending them.

This may be of some help also.
