ICM & Nortel CCMS 6

Unanswered Question
Mar 30th, 2010

We are attempting to connect Cisco ICM to our Nortel Symposium/CCMS 6 server, BUT the two devices are separated by a firewall. I have been able to find documentation regarding the multicast configuration on the Nortel side, but nothing using unicast through a firewall.

Has anyone attempted this before, or does anyone know of documentation for port/firewall requirements between the two devices?



I have this problem too.

Hi James

Did you get any input on this..? Were you able to solve this issue...?

We came across a similar issue as well... Any thoughts will be helpful.

We were finally able to get this working--I only have access to the configuration on the Nortel side however. This is what I have open inbound on my firewall--I am not filtering outbound (Nortel-->ICM):

service-object tcp eq 3000

service-object tcp eq 1550

service-object tcp eq 4905

service-object tcp eq 30000

service-object tcp eq 10020

service-object tcp eq 135

service-object tcp eq 10000

service-object tcp eq 10023

service-object tcp eq 10024

service-object tcp eq 10025

service-object tcp range 1024 5999

service-object tcp eq 10013

In addition, data compression for the RTD/Real time reporting service on the Nortel/CCMS side MUST be disabled or the ICM box will never connect to CCMS.
I'm not sure if this is helpful at all, but this is the experience I can share.

Thanks James.... When i had put a wireshark... I am seeing an ICMP traffic from the PG to the Nortel everytime when I start the service... were you experiencing any similar traffic...?

Best Regards
