Problem with getting through sip.voipbuster.com

Hi guys,

It's my first time here, Ihave to say it's nice little forum.

I am form Uae, the country with telecom monolpoly where internet and telephone prices are over the top. In order not topay exorbitant price I decided to use voipbuster which works fine from PC but I do have problems with using sip phone Ecom Tc-300

I have d-link router 2640T which has most sip ports open (checked with voipbuster software). I have problem connecting sip.voipbuster.com as my ISP is directly blocking the domain. Is there any cheap alternative like using proxy and sTUN to get around this?

(P.S around 99.9 percent of proxy servers are blocked here)

I understand it's even suspected that people from the national provider may monitor the internet to keep up with the state of the art about work-arounds.

I don't know myself, but chat to telecom nerds amongst the expatriate communities there
