Ports required for voice gateway registration

Hi,

Currently our remote office voice gateway is trying to register to the CM and in between there is a firewall. We have opened port DNS, NTP, 2427 and 2428 but it still showing registering to the call manager. What other ports shall we open to make it works?

What about the port requirement for CUE?

Thanks.

For MGCP:

DNS

NTP

UDP 2427

TCP 2428

TFTP (UDP 69)

For CUE, here is a link you may find helpful:

Re: Ports required for voice gateway registration

Hi Nick,

Thanks for your reply and I will try out for the MGCP tonight.

Btw, seems like the URL needs special privilege to access... is there any public documents I can refer to?

Thanks again.
