我刚刚设置了 Asterisk 的服务器，但是当我尝试拨打 VoIP 电话时，线路自动断线......
我使用 CommPeak 作为 SIP 提供商，使用 Bria 作为界面
这是我的sip.conf：
[general]
allowguest=no
context=default
bindport=5060
dtmfmode=rfc2833
disallow=all
allow=alaw
allow=ulaw
allow=gsm
allow=g723
allow=g726
allow=speex
; replace INBOUND_SIP_USERNAME and INBOUND_SIP_PASSWORD
; with your Inbound SIP Registration credentials
register => USERNAME:PASSWORD@trunk
[9786324654]
type=friend

context=from-internal
username=USERNAME
password=PASSWORD

[8763442]
type=friend

context=from-internal
username=USERNAME

[trunk]
type=peer
host=eu1.sip.commpeak.com ; Europe POP
;host=amn.st.ssl7.net ; North America POP
context=from-trunk
qualify=yes
defaultuser=USER
remotesecret=SECRET
我的 CommPeak 有足够的信用来拨打电话
