I have inherited a number of Asterisk servers running Asterisk SIP Phones in several offices at the company I am currently working with. I am currently running:
Asterisk 220.127.116.11 ON CentOS 4.4
As far as I know, there is no GUI front end and I can only configure anything from the CLI.
One of the offices is moving location and as part of this, they are also changing the phone numbers.
1- Do I need to make any changes inside Asterisk?
2- How and where?
I hasten to add, that I'm not a telephony engineer, so a lot of stuff is a bit foreign to me. I am a Windows engineer really :)
Please could anyone help?
