Hi,
I got the newest 3CX PBX Pro Edition installed on Debian 9. We do have 4 NICs installed, eth0 for WAN and eth1 for LAN. eth2&3 not used yet, and not configured.
eth0: WAN IP
eth1: 10.2.2.1 without default gateway
Extension 251 IP: 10.2.2.3
ISC DHCP Server is running on the system, with option 68 for auto-provisioning. This works perfectly.
Now when I try to call someone, it doesn't matter if it's another extension or an external number, I get the error 499 "Caller is forbidden". Here is a tcpdump from a call that was from extension 251 to 278:
attached text file: tcpdump_caller_forbidden.txt
Here is the log from the 3CX:
Extension 278 is not provisioned via 3CX. It is connected via WAN and just SIP Username/Password. Extension 278 can call 251 but 251 can't call back. 251 can call nothing, not even other auto-provisioned phones. Other auto-provisioned phones can't call neither.
Every phone is a Yealink T46S.
BUT when I use the 3CX Windows Client in Softphone mode, I can call whatever I want.
Do you need any further information?
I just need to know why the 3CX PBS sends the Code 499/"Caller is unknown" and how I can prevent this.
Thank you.
JL

Extension 278 is not provisioned via 3CX. It is connected via WAN and just SIP Username/Password. Extension 278 can call 251 but 251 can't call back. 251 can call nothing, not even other auto-provisioned phones. Other auto-provisioned phones can't call neither.
