Networking two mitel 250

[berkley]

I am networking two mitel 250s. The ports I have forwarded are:

Ports:         Connection Name:

67, 68 UDP        DHCP

69,20001    UDP       TFTP

6800-6802 TCP      SAC protocol

5004-5007 UDP      RTP Intertel

50098-50508 UDP      RTP Minet

6004-6261 UDP      RTP

6604-7039 UDP      RTP

3998-3999 tcp      SAC

5566            tcp

5567            udp

5570            tcp


Remote Access Ports

22 TCP
80 TCP
443 TCP
4000 TCP
4444 TCP
44000 TCP

Are there any other ports I need to open? I am getting a communication error.
The systems are new and use sip.

Thanks as always!!

berkley,
Are these systems on a vpn, using internal addresses or using public addresses across the Internet? The ports you've opened are primarily for off-site IP phones.
I don't believe we've ever had to open/forward ports unless the customer had completely locked down their VPN. The problem we've usually had, if all ip addressses are correct, is the numbering of the IP Connections. In node 1, we usually number them 6000 (and if there is a PEC, 6010). Then in Node 2 we number them 6001 (6011 for PEC).
Then check your Node Connections in Node Connection Groups that each node is represented by the correct Node Connection Extension.
Hope this helps.

MiVoice Office 250's cannot be networked via NAT or port forwarding... You must have a VPN or other directly routable networking solution.

A tip on IP Connection numbering: always have the last two digits equal the node number.

Node 1 is P6001, P6101, P6201; Node 12 is P6012, P6112, P6212; and so forth.  Use Px00 for miscellaneous connections, such as a CT Gateway. You can build all 99 nodes and not screw up your numbering plan.

Thank you for the reply's. Tomorrow I will build a vpn between the two and open ports for offsite phones.
