UC520 Dialing Plans

We sometimes use an extension for testing out modems, so rather than having to add a ‘9′ to the start of the ISP phone number, it would be nice to be able to dial straight out.

Here the ISP numbers start with 0867, so I thought why not create an outgoing dialing rule which doesn’t require an access code.

I created a rule with the access code 0, number beginning with 867, 8 digits long, and set it to forward the access code to the trunks. This works great, except my incoming dial plans no longer work! Instead of SIP calls going to the auto attendant, they just get a busy signal. The moment I remove my outgoing dialup internet rule it starts working again. Haven’t had time to find out the actual cause for this, but I’m guessing it is a gimmick because I was using the GUI to configure it.

I had been pulling my hair out with why auto attendant wasn’t working (I didn’t want to specify the SIP number in the auto attendant setup because we have several numbers that should terminate to the same AA) and rebuilt the system today, which is when I discovered what was causing the problems.
