[Asterisk-Users] gnophone

[Eric]

I am having a really hard time getting gnophone working with asterisk. 
Gnophone tries to register with my server but there is no response.  I
can direct incoming calls to gnophone but if gnophone answers them,
asterisk does not recognize it.  Here is my configuration:
iax.conf
[jambo]
type=user
host=dynamic
defaultip=136.159.99.100
permit=136.159.99.100
username=jambo
secret=fubar
context=gnophone
password=fubar

extensions.conf
[gnophone]
exten => 2108407,1,Dial,Zap/1|BYEXTENSION
exten => 2108407,2,Dial,Zap/2|BYEXTENSION

My gnophone telephone preferences:
Server: 136.159.99.74
Port: 5036
Context: gnophone
Username: jambo
password: fubar
Peer: jambo
Secret: fubar


please, please, please if anyone can help....
