SIP Trunk ITSP

[clark white]

Hello,

I am trying to setup a new sip trunk (new connection) to ITSP, whenever i dial a PSTN number i get a fast busy tone, My ITSP says everything is OK from their end,

Can anybody refer me for step by step troubleshooting docs for such type of issue.

Question 1, yes your config is correct..

Question 3, It is the recommended solution to use sip trunk to the CUBE rather than h323...
