Hello
I have SIP trunk to a company which supports 3CX. Now I want connect FreePBX distro (latest version) to the trunk. Unfortunately the company does not provide much details. All I know:
VoIP ID: 7483xxx
Password: xxxxx
SIP registration URL: sip.3cx.voipworld.org
NAT proxy URL: nat.3cx.voipworld.org
I have congifured one inbound, one outbound routes and one trunk.
Trunk:
Trunk Name: voipworld
Outbound CallerID: 08723324xxx
-
Outgoing Settings:
Trunk Name: voipworld
PEER Details:
username=7483xxx
type=peer
secret=xxxxx
host=sip.3cx.voipworld.org -
Incoming Settings:
USER Context: voipworld_incoming
USER Details:
type=peer
insecure=invite
context=from-trunk
outboundproxy=nat.3cx.voipworld.org -
Register String:
7483xxx:[email protected]/7483xxx
Asterisk is registered:
Host dnsmgr Username Refresh State Reg.Time
sip.3cx.voipworld.org:5060 N 7483xxx 105 Registered Wed, 06 Feb 2013 16:34:18
Outgoing calls work fine but I can not receive incoming calls. Robot on provider side tells there is an error and I see nothing in SIP debug on Asterisk. Guys from support told me “You need to setup the outbound proxy of nat.3cx.voipworld.org (Port 5060) for incoming calls to route.” But they give no other info because they do not support Asterisk/FreePBX. I added outboundproxy=nat.3cx.voipworld.org to incoming details but it did not help.
Any ideas?
Thanks.
