  5. Multiple IP devices on a subnet

    There are two IP devices on a subnet. They're of the Mitel type, but it doesn't matter. The basic problem is that both extensions log on to the 3CX subcenter on port 5060. They can't call each other. Mobile extensions works, but I can't bring more than one IP device to life. With port...

If I try to access the port (port:5001 lets say) from my remote Unifi location I can't access the main location that uses a Cisco system we...

  8. Firewall port closed - RTP still flowing

    Hello, Let's assume the following simple setup: Internal 3cx (RTP port 9000) - - - > Firewall - - > Internet - - > Provider (RTP port 10000) The internal 3cx has a SIP trunk with the provider and UDP port 5060 is open on the local Firewall, so SIP negotiation is OK. However, RTP port 9000 is...

    SIP traffic is not allowed

    Hi every one, ISPs are blocking SIP traffic, as a result, we can't use 3cx remote apps, and it's ridiculous to ask customers to use VPN app whenever they are willing to connect remotely. We tried to use different Ports instead of 5060 and 5090 but still no luck. did anyone come across a...

    RTP PORT management

    Since the upgrade to version 15.5 SP5 the range of RTP ports has varied and now they are from 9000-10743. This is too large a range for PBXs that are not for 1024 concurrent calls. In clients of 4, 8, 16, 32, 64 it is not necessary to use such a wide range of ports. This generates...

    First time using a hosted PBX. It will have 3 different locations. I've got three raspberry pi's setup as SBCs. Do I need to setup any forwarded ports? They seem to work fine but I don't want to have intermittent problems down the road.

  19. Changing Port Numbers for testing

    I am wanting to test 3CX on a local install, but we currently have another IP phone system live in production, that is using some of the default recommended ports. Does anyone know of any issues that I might incur if I just add a 1 to the port numbers, instead of 5001 > 15001 for HTTPS etc...

  20. Restricting inbound traffic

    Hello all, I'm hoping I can set a firewall rule that will enable me to restrict inbound traffic from the 3cx pbx public ip addresses (for ports 9000-9500) to only allow the 3cx traffic to be forwarded to my internal network. Having read the set up instructions it looks like 3cx have said to...
