International calls are not working over sip trunk

[Syed]

Dear All,

Due to some reasons we have requested to our ISP to block all international calling for a couple days.

Now international dialing is restored by ISP and confirmed, but we are unable to make any international call and I am receiving the below error from ISP. Any help would appreciated.

Hi,

If calling and called number in INVITE message is in accordance to your provider and still you are getting 403 Forbidden, you probably need to check with your provider.

Hello Vivek,

Issue is fixed now. The problem was on telco side and they activated international calling.
