Internal Calling to DID Issue

[KyleKSIP]

I have an internal extension 101 trying to call the DID of their other location connected via SBC which should ring extension 201 at the other location. Instead I get a fast-busy call failed tone... calling externally into DID works fine and calling internally from 101 to 201 works fine. Any Ideas?

Also tested this inhouse. From my extension I tried calling a DID of another tech in our office and experienced the same results. Calling his internal extension number worked without issue

How are you expecting this call to route...use outbound rules, route to your provider, then back in on another trunk?

Or, are you going Direct SIP, dialling the SIP ID of the destination?

Check the 3CX Activity log, to see why the call is failing

Hi @Kerby,

What is your use case? Why not just dial internally?
