Hi all,
We have a Mitel 5000 system. I have recently moved locations and therefore routers.
I am working from a 4G TP Link router with a Virgin Media unlimited data sim (it is in the countryside and no decent ISP) Plugged into the router is my 5312 IP Phone. Signal strength on the router is good.
At my previous location everything works fine when the phone is plugged in.
At the new location people
can hear me but I cannot hear them. The phone makes external phone calls but again no dial and no sound from the other side.
The phones IP address is 192.168.1.106. Port forwarding is set up as follows:
ID Service Port Internal Port IP Address Protocol Status
1 6004-6261 6004-6261 192.168.1.106 UDP Enabled
2 6800-6802 6800-6802 192.168.1.106 TCP Enabled
3 3998 3998 192.168.1.106 TCP Enabled
4 3999 3999 192.168.1.106 TCP Enabled
5 50098-50508 50098-50508 192.168.1.106 TCP Enabled
The above is the same configuration used at the previous location.
SIP ALG is disabled as well as SPI firewall. I have also enabled DMZ to point to the phones IP.
I am not a technician but have a basic understanding, a company manages our Mitel 5000 system but they have come up blank on this occasion
They have also confirmed everything is set up on the Mitel 5000 system correctly and nothing has changed since I have moved ... I even took the phone back to the previous location and all worked fine still.
