[cisco-voip] Expressway C&E issue

[NateCCIE]

You need to use the newer docs.  The port list changed for media.

Not a security or a firewall guy so please bear with me.

 

We've opened up the ports as advised in this: http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-1/Cisco-Expressway-IP-Port-Usage-for-Firewall-Traversal-Deployment_Guide-X8-1.pdf

 

Now, the weird part is that with a jabber client on the internet we get no RTP with this configuration.  Only when we open any to the Expressway-E do we get RTP, however we don't get signalling to the jabber client on the internet.  

 

Are there any other ports we should be opening?

 

I was under the impression that creating the UC Traversal zone opened up the logical channel between the C and the E so that everything outbound to the internet could get to the DMZ and out to the internet.  Am I misunderstanding?  Is there more configuration I need to piece together to make the solution whole?

 

Thanks in advance!
