asterisk users - Oct 2004 - first tries !

I just setup two ip phones..
The problem is that when they connect trough asterisk nothing
is heard or sometimes garbage.. both phones are set on uLaw,
With or w/o allow=ulaw in sip.conf
the result is the same...

If I set canreinvite=no, then everyhtink works..
what is the problem ?!? a solution

The problem is SIP NAT traversal

The solution is 'canreinvite=no'

for more information on why SIP and NAT are enemies, search the Wiki
for "NAT Traversal" (the URL is http://www.voip-info.org)
