Traversal Subzone Media Port range - Expressway

Dear Community

 

On the Expressway IP port document  for traversal it said the the lower 12 ports are use (From default 36000 - -59999 range - 36000 to 36011). When configuring Expressway it shows 36000-36012 as the ascent RTP/RTCP port.

 

Why port 36012 is included?

Which guide are you using?  There may be a typo in some of the earlier guides which was fixed in the newer ones.

See Cisco-Expressway-IP-Port-Usage-for-Firewall-Traversal-Deployment-Guide-X12-5.pdf for the latest one as of the date of this post.

Hey

 

I have x8.11.4, then i am using x8.11.1 ip Port document. That's the only one available for x8.11.x.

 

https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-11/Cisco-Expressway-IP-Port-Usage-for-Firewall-Traversal-Deployment-Guide-X8-11-1.pdf

 

Expressway release notes are very specific on version since they are implementing MANY changes (and features) between releases (even between minor releases). A few ports changes across releases also...

 

About the ports, my x8.11.4 shows assent traversal 36000 to 36012 but document shows 36000 to 36011.  That's what i am looking for?
