I have a weird problem. I assume its firewall related since it happened after I moved the phone to another network.
I have a Grandstream GXP2170 thats in an office offsite. I have about 20 extensions there working fine including this extension. My PBX is running on a virtual server in another state. All the phones work without issue. I move one phone to a home office. I can call this extension from any other without any issues and carry on a conversation without issue. If I try to make an outbound call i get an error message “no response” on the display and a busy signal. In free PBX I can see the extension is registered and everything looks normal from all perspectives I looked at. The home network is a high speed fiber (FiOS) from verizon and I checked he firewall and it has an outbound policy of allowed and an inbound policy of reject. I assume this means it allows all outbound connections but rejects “unsolicited” inbound connections (remember, if I call the extension it works fine). I have another office also with Verizon FiOS and same firewall) which works in and out no problem?
- I have updated the firmware on the GXP2170 with no difference
- I have verified the IP of the home office is in my whitelist.
- Endpoint manager shows the extension as registered (with the IP thats on my whitelist).
- When the extension is trying to dial out, I see nothing in the asterisk log
- Firewall has no restrictions on outbound connections
- This extension (109) cant call any other extension or outside number
- If I reboot the extension (109) I see the phone “unreachable” in FreePBX logs, when it boots up is see “109 now reachable” in the log
Distro freepbx 14.0.11 (asterisk 13.22.0), basic setup all I did was add extensions (PJSIP) and SIP trunk.
Suggestions? What else should I look at?
