Traversal Subzone Media Port range - Expressway

[aalejo]

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.

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?
