HELP: Outbound call to China not working


i am using FreePBX 2.11 with Asterisk 11.5 IP PBX system.

We would like to have a local calls to china, so we arranged a testing on 1 on China’s voip provider. We were given a test account by a Chinese voip provider, created a SIP Trunk, inbound and outbound route for it.

We’ve managed to register our PBX server to the voip provider using their supplied username and password. inbound calls to our China DID seemed to be working, but outbound call to China using our China SIP trunk was not. Whenever i tried calling China number, i am getting a message “all circuits are busy now, please try your call again later”. I also noticed on asterisk CLI that it’s trying to use other SiP Trunk instead of the China SIP trunk.

if i may ask, what would be the correct Dial Pattern for trunk and outbound route? the Chinese voip provider mentioned that i can just use “X.” (without quote)

Any help is greatly appreciated

Thanks in advance…
