I wonder if you could help us with the phone configuration in Dubai.
We have a 3CX phone system in the Uk
We’ve just rented some space in a service office in Dubai
And have arranged for Port 5060 (inbound, UDP) for SIP communications and
Port 9000-10999 (inbound, UDP) for RTP (Audio) communications to be opened on their firewall and linked to the IP addresses of the phones in the office.
We are told that the public ip is 220.127.116.11 which can be used to access the services (I don’t under this part)
However the phone are showing a SIP error and not currently working.
We’ve only two full days left in the Dubai office and I am reaching the edge of my understanding.
Would you be able to assist ?
