[asterisk-users] can't call through voip provider

Wed Nov 18 16:54:55 CST 2009

To be perfectly complete, exactly which inbound ports to open will depend on the phones in use.  For example, a Cisco 7940 (using this example because I have one on my desk at the moment), the default ports from the config are:

voip_control_port : 5060
start_media_port : 16384
end_media_port : 32766

Meaning, you have to have 5060 open (obviously), and all the ports between the start and end media port.  Many phones will let you adjust where these boundaries lie, but some won't.  You'll need enough range to cover every kind of phone (soft or hard) that you are using.

Ok. I do NOT have ports 10000-20000 opened in. I guess I should try that and see if it works.

I will open ports 5060 - 5070 and 10000 - 100100 and do some test tonight. I will keep you posted.

Thanks.
