Need Port numbers 2

I am placing a remote i2002 ip phone that is behind a firewall.

What ports do I need to open on the firewall to ensure correct signaling and talk paths?

Remote location i2002 --> Firewall --> MPLS --> Main Location Firewall --> Main Location Router --> Nortel Signaling Server/Other IP & TDM phones

 
you would figure that out by watching a phone and seeing which port it is trying to use. Can you monitor your switch/router?

The phone is not in place yet. Goes into production Thursday. I know I could figure it out by sniffing traffic or by scouring NTP's, but I was hoping someone already had the knowledge readily available to share. If not, then I'll manage on my own, it will just take more time.

I know there are several people in here who probably set phones in this scenario regularly and could rattle port numbers in their sleep.
 
sorry, thought it might be arbitrary depending on setup. CS1000E - ports 4100 and 4300

I know the 4100 port, I'm curious as to what else needs to be open, if anything, for talk path and/or signaling.
 
My Nortel Rep sent me this nice spreadsheet, so I thought I'd share:

Code:
Nortel VOIP Ports			
Component	Port Type (signaling , voice,  probe, etc)	IP protocol (TCP/UDP)	Port number or range
CS1000			
Registration	signaling	RUDP	4100 / 7300
Signaling (Unistim)	signaling	RUDP	5100
UFTP (firmware download)	signaling	RUDP	5105
Line side - 32 port media card	voice / RTP	UDP/RTP	5200-5262 (even)
Line side - 32 port media card	voice / RTCP	UDP/RTCP	5201-5263 (odd)
Line side (when using 96 port DSP)	voice / RTP	UDP/RTP	5200-5390 (even)
Line side (when using 96 port DSP)	voice / RTCP	UDP/RTCP	5201-5391 (odd)
Line side (when using 96 & 32 port DSP)	voice / RTP	UDP/RTP	5200-5454 (even)
Line side (when using 96 & 32 port DSP)	voice / RTCP	UDP/RTCP	5201-5455 (odd)
PRI Gateway (with 2 96 port DSP)	voice / RTP	UDP/RTP	5200-5582 (even)
PRI Gateway (with 2 96 port DSP)	voice / RTCP	UDP/RTCP	5201-5583 (odd)
Trunk	signaling	UDP	1718-1719
Trunk	signaling	TCP	1720
Trunk	voice / RTP	UDP/RTP	2300-2363 or 17300-17363 (even)
Trunk	voice / RTCP	UDP/RTCP	2301-2364 or 17301-17364 (odd)
Trunk QOS monitoring	QOS probe	UDP/RTP	5000
SIP	signaling	TCP & UDP	5060
			
IP Phones -> CS1000			
Registration	signaling	RUDP	4100 / 7300
IP Phones - CS1000 	signaling	RUDP	5000
Signaling (Unistim)	signaling	RUDP	5100
UFTP (firmware download)	signaling	RUDP	5105
RTP (media)	voice / RTP	UDP/RTP	5200
RTCP (signaling)	voice / RTCP	UDP/RTCP	5201
Signaling (Echo server)	signaling	RUDP	10000
TFTP (firmware download)	signaling	TFTP	69
IP Phones - WLAN	voice	UDP/RTCP	IP Protocol 119
 
Hi Pal, it will be helpful and easy to read if you paste here in excel form or as an attachment.
