I’m configuring a new install of 3cx V8. I have run into a couple of issues and wondered if there was a way to accomplish the following. I have my 3cx connected to an Avaya S8730 via sip trunk. I’m using 3 digit dial plan on the 3cx and 4 on the Avaya. Users are used to dialing DID numbers into the Avaya that now can be reached via the sip trunk. I want to create an outbound rule on the 3cx that if a user dials a number xxx-xxx-xxxx the digits are dropped and replaced with the corresponding 4 digit extension. However, in the outbound rules, I only see the ability to delete a maximum of 9 digits. Why is 9 the max? Is there a way to change this? Second question is on inbound routing. I created a VOIP connection on the 3cx for incoming calls from the Avaya and added a DID for that trunk. On the voip provider port page, I have to select where the call is routed. Of the limited options, the one that I selected is connect to extension. I have to select a static extension that all calls that come into that trunk are routed to. How can I get a call that comes in that trunk to route to the extension that was called? I see the correct extension in the INVITE, however the system ignores that and routes the call to the static extension specified in the voip did config.
