I’m a telecomms professional, but I am afraid to say I feel like a complete amateur with this system. I’ve read through so may threads and documents but I cant find the REALLY basic stuff to get me going. I get 99% of the FreePBX config as it’s standard PABX setup, but I cant get to do the simple thing of connecting a SIP phone (soft or hard) to Asterisk.
I need a real dummies guide to SIP. Like, does the SIP phone need to register with Asterisk? If so where in Asterisk do I set up the user name and password? (Do I need to set up a user name and password??) If I set up an extension I can only see where I set up a “secret” - presumably this is a password for the client?? What is the Deny field for? If my SIP phone has a fixed IP can I set this up in Asterisk somewhere?
What I need is someone to imagine I have NEVER worked with SIP, but have worked with TDM PABX all my life, to tell me how to set up extensions both at the extension end, and the Asterisk end.
Whats a registrar? What is an anonymous connection? Where do I set up the asteisk details in the cliet? where do I set up the client details in asterisk?
Sorry guys I know you are rolling your eyes and sighing, but I need to tell you for a new entrant into SIP/Asterisk I am at the point of giving up.
Anyone fancy becoming my mentor?
Just to bottom out the obvious questions :- Asterisknow install on a VMWare virtual machine using CentOS (CentOS, asterisk, and all the other stuff out of the box), configuring Asterisk via FreePBX, trying to use a Swissvoice IP10s SIP phone, SIP Communicator softphone, and a Phonerlite softphone. Getting nowhere.
