[asterisk-biz] Asterisk to Gateway in Asia?

[Sip Pabx]

Hi All,

We have Asterisk installed in our setup with 20 VOIP Clients. we are able to use it as expected.

Now we want to Extent our Asterisk so that we can make International Calls to Asia (Sri Lanka, India , Singapore....)

Can any one help me in referring me to the provider/Links who will help me in Routing my VOIP Calls (SIP from Asterisk Located in USA) to a Gateway in these countries.
I am sure it should be possible, but after searching  also I could not find.
Also will it be expensive?

Waiting f your reply on this.

Regards,
Matengi.
