Greetings!
I have a Mitel 6867i that I am trying to remotely connect to my FreePBX server as extension 4010. It seems to register with Asterisk but all calls in or out fail.
PHONE SETTINGS
Under Advanced Network Settings, I changed:
- NAT IP: server’s external IP address.
… and nothing else under that heading. I see there is NAT SIP Port and NAT RTP Port pre-set in the 51000 area (both different). Are these the 10001-20000 port range set up in my firewall? I shouldn’t have to change these, correct?
In Global SIP Settings, I only changed:
-
**Proxy Server** to the server's external IP address
-
**Proxy Port** to the BIND port set in FreePBX under Asterisk SIP Settings
-
**Registrar Server** to the server's external IP address
-
**Registrar Port** to the BIND port set in FreePBX under Asterisk SIP Settings
I did not enter any user/pass info here.
Under Line 1:
-
**Phone Number** 4010
-
**Authentication Name** 4010
-
**Password** its-a-secret
FreePBX Settings
I should mention that in FreePBX under extension 4010, I changed:
- Secret to its-a-secret
- NAT to Yes
- Port to the same as the BIND port set in FreePBX under Asterisk SIP Settings
- Qualify to Yes.
I know it’s old but it works:
PBX Firmware: 1.812.210.57-1
PBX Service Pack: 1.0.0.0
Also, I have several softphones that connect to this server remotely with almost no issues so I believe the port forwarding is all correct.
Could you offer a suggestion as to why this isn’t working?
Thanks in advance!

EDIT:
In Asterisk -rvvvvvv, I tried to make a call to a custom config extension (one that will play my on hold music) *135 and received the following:
[2017-05-25 11:44:02] WARNING[2939]: chan_sip.c:8916 process_sdp: ignoring ‘audio’ media offer because port number is zero[2017-05-25 11:44:02] WARNING[2939]: chan_sip.c:9124 process_sdp: Failing due to no acceptable offer found
Same thing when I call another local extension. I hope this provides clues.
EDIT 2:
Interesting!
When I perform the setup, everything seems to work fine (extension calls, RX, Outbound, custom extensions)… until I reboot the phone. Then the Call Failed shows up again. All of the settings appear to be intact.
