Problem with internet gateway

i connect to sip server connected in india but i couldnt connect to sip server located in US
can anyone faced this problem…
thanks in advance

This probably has to do with either your ISP or the VOIP provider. Can you connect to other providers in the US ? Also contact your ISP.

i cant connect to any us sip provider but i connected with indian sip provider who has their server in india

Then this probably a restriction by the providers in India to keep all the business local so that you do not go to the competition. You can do two things.

  1. Ask the provider to offer VOIP on alt. ports
  2. Put a server some where, where they dont restrict your internet usage and then connect to that server from India on an alt. port.
