I have a SPA3000 and Asterisk running quite nicely after about a week playing around. The only serious problem I'm having now is that SIP channels to dialpad do not close.

I run Asterisk on a Fedora box which is also my firewall, so it has a public IP address. iptables is set to allow RTP and port 5060 thru on udp. The call itself is fine, as are calls thru the PSTN and sipgate.

sip.conf reads:

[dialpad]
type=peer
auth=md5
md5secret=x
username=x
fromuser=x
host=66.35.222.58
rtptimeout=60

extensions.conf reads:

; international dialpad
exten => _00X.,1,Dial(SIP/${EXTEN:2}@dialpad,60,)
exten => _00X.,2,Congestion

The open channel reads:

baggygreen*CLI> sip show channel 45
baggygreen*CLI>

Any ideas appreciated.
