I would like to use the PSTN line form he SPA-3000 as a gateway for local calls.
So i made an extension phctelecom-106 where the SPA-300 PSTN line can register
Then i made a trunk which uses phctelecom-106 and sip server is dynamic
But when i make an outbound routing for it and i call anything that will be routed to that trunk i get all circuits are busy now. Could someone help me with this.
