asterisk users - Feb 2006 - nat=yes and qualify=yes viable NAT solutions?

Looking for some feedback on whether nat=yes and qualify=yes will
provide a workable solution in many cases?

 

The * server is on a public address, no NAT, the UAs (sipura, linksys,
polycom) are behind various types of NAT.

 

Obviously port mapping in the NAT device works, but what about cases
where there is no admin access possible to the NAT device?

 
>From what I have read nat=yes makes asterisk look at the udp header
instead of the SIP info for the UA IP address, and qualify=yes sends
keepalives in the form of frequent SIP OPTIONS queries. I think I also
read that nat=yes enables symmetrical RTP

 

What I do not know is does it work in the real world?

Sipura works, I never tried linksys, Polycom might and might not work.

Thanks, the linksys is a sipura, so what works on one should work on the
other.
