After setting up my basic SIP PBX with 2 extensions, I still have some unresolved issues.
Asterisk 1.0.7 and a Sipura SPA-2100.
(1) The passwords are irrelevant. During setup I kept on getting the dreaded “SIP/2.0 403 Forbidden” message. Obviuosly, my first guess was that perhaps I had a user id/password problem. It turns out that the problem was elsewhere (See (2) below)
(2) I paid Comcast to have several public IPs in my domestic network, in order to experiment comfortably with Asterisk (the server is at the office with at T1, the phones are at home). Since I have plenty of public IP addresses, I placed the following line in the sip.conf file:
host = 24.128.127.93
That was a big mistake. For several days I kept on getting the dreaded 403 Forbidden message. The solution? Simple (a posteri, of course) but not obvious:
host = dynamic
I do have another fixed (non-dynamic) IP device, a Cisco AS-5300, but that one is configured as “peer” instead of “friend”. It works perfectly and I never got the dreaded 403.
(3) When I dial my very own extension from itself, I expect to hear a busy tone. I get dead air instead.
Thanks for your insight in resolving these issues.
