[Asterisk-Users] Newbie - getting two local phones tocommunicate would be a good start :)

[Philipp von Klitzing]

Hi!

You started out with a much too complex setup. Start small, test, and 
then add things step by step - don't configure everything at once!

> Asterisk and 2 Grandstrem phones on a LAN. The * box (liza) is RH9 and

Then remove the nat=yes statements (and also the reinvite= and 
canreinvite= parts) - for Asterisk your phones are not network address 
translated. Also I guess you already read somewhere that having Asterisk 
behind NAT is cause of trouble - but that doesn't matter for your 
internal testing with a basic setup. 

After adjusting sip.conf don't forget to "reload" Asterisk.

> externip = 10.0.1.198

Remove this for the time being to get your internal test running. Leave 
messing with externip= for later.

See the disallow and allow statements I added in sip.conf.
