Twinkle won't Register with Asterisk

Asterisk Asterisk Support
1

I have a CentOs5 Asterisk installation ver 1.6.

The Asterisk installation is on IP 192.168.0.202
and a Twinkle Softphone is on 192.168.0.2.

I can’t get Twinkle to make a call to, or register with Asterisk.

I have a test dialplan on the Asterisk server that I want to dial into. The dial plan is functioning when dialed from the CLI (CLI> console dial 1001).

# cat extensions.conf
[default]
exten => 1001,1,Answer()
exten => 1001,2,Playback(hello-world)
exten => 1001,3,Hangup()
...

I am new to Asterisk so I don’t know if I have the Twinkle set up wrong or if it’s an Asterisk issue, or what.

I noticed the following in twinkle.log:

+++ 27-10-2010 22:38:57.994886 INFO NORMAL ::listen_udp
Received ICMP from: 192.168.0.202
ICMP type: 3
ICMP code: 10
Destination of packet causing ICMP: 192.168.0.202:5060
Socket error: 113 No route to host
---

Any help appreciated.
Are there settings I should be checking with:
CLI> Sip show settings
?

Turned firewall off and added:
include => default to extensions.conf

# cat sip.conf
[general]
port=5060
bindaddr=0.0.0.0

[frank]
type=friend
secret=password
host=dynamic
register => password@192.168.0.202/100
context=internal

# cat extensions.conf
[default]
exten => 1001,1,Answer()
exten => 1001,2,Playback(hello-world)
exten => 1001,3,Hangup()

[internal]
exten => 100,1,Dial(SIP/frank)
include => default   ;; added line

Firewall needs to be fixed now.

fixed the firewall by adding the following iptable entries:

ACCEPT udp – anywhere anywhere state NEW udp dpts:ndmp:dnp
ACCEPT udp – anywhere anywhere state NEW udp dpt:sip
