I have a FreePBX 188.8.131.52 system that currently has [1-7]XX and 1[5-6]XX and 8XXX extensions. I have just become the phone administrator. I need to move to 4 digit dialing. I would like to use the first digit to identify department, i.e. 2XXX Admin, 3XXX Audit/Finance, 4XXX HR, 5XXX IT, etc. I would like to accomplish this by appending the 4th digit to the front of the current 3 digit extension for the most part and use Find Me/Follow Me to redirect 3 digit calls for a set period of time.
We use primarily Aastra/Mitel phones with a few older Polycoms. All phones have the same dial pattern on them:
I have been trying to modify this string to no good purpose. I am using 378 - no current end user - and 3781 - newly created extension without an end user yet - as a test and get the expected system response when dialing 378 but getting call failed on 3781.
I have worked with VoIP and IP Telephony for years now. I am primarily a data guy though, not a phone guy. I am finding this challenge to be frustrating. I would really appreciate any and all tips. I have sought guidance from boards for years, this is my first attempt to actually post on one.
