VoIP Connectivity Restored?

Update 11am Belize ST June 7th 2006 – SIP appears to be down again:

Test results from TestYourVoIP.com

Test yours NOW. Comment below on your findings.

———————–

Your computer couldn't call our location on the standard SIP port (5060), but did successfully communicate over a commonly available port (6000). This suggests that an application or firewall is blocking our SIP access. Please check the following:

  • If you have a VoIP Service, your VoIP/Phone Adaptor may have reserved the standard SIP port and is filtering out our SIP packets. Consider temporarily removing the Adaptor from your configuration and re-running the test.
  • Your Personal Firewall, if you are using Windows XP, may be filtering the SIP port used for communication.
  • Either your home firewall or your broadband provider's firewall is blocking the SIP port used for communication.

Please check these firewall settings and ensure that UDP ports 5060 and 50000 – 50100 are open for RTP streams and SIP signaling. Then re-run your test.

We have heard from many of you that SIP-based services (VoIP) are working again in Belize. We just disovered that our connections to TestYourVoIP.com, which were totally blocked before, are now reporting SIP connectivity with good bandwidth/codec quality. If you are in Belize, please test your own and report your findings in a comment on this post. You can test from various locations, I happened to pick Boston.

Mine was taken 7:25PM Belize Standard Time June 6th, 2006.

    very interesting, but I don’t agree with you

  2. I was wondering if you ever considered changing the layout of your website?
    Its very well written; I love what youve got to say.

    But maybe you could a little more in the way of content so people could connect
    with it better. Youve got an awful lot of text for only
    having 1 or 2 pictures. Maybe you could space it out better?

  3. This is very interesting, You are a very skilled blogger.
    I’ve joined your rss feed and look forward to seeking more of your great post. Also, I have shared your web site in my social networks!
