[ILUG] Asterisk woes

[Niall O Broin]

I have been using Blueface as my phone provider for a few years now, with phone service at home provided through a Linksys WRTG54P2 which is a WiFi router with two integrated FXS ports, which is registering directly to Blueface. I want to start using an in-house asterisk server but I am having no success in getting the Linksys to work with it.

I can setup calls, but I get no voice, in either direction. I can use soft phones registering to the asterisk server, both the Mac application Telephone and X-Lite, and they work perfectly, both for internal calls and for external calls, originating and receiving. 

I thought this might be some peculiarity of the Linksys so I replaced it with a Handytone HT502 2 port ATA adapter which I had handy ;-)  and sadly, it suffers from the exact same problem as the Linksys - call setup is fine, but no voice.  If I initiate a call between a hard phone and a soft phone tcpdump shows me UDB packets whizzing back and forth between the two, but I guess they're not speaking the same language, for whatever reason.

The asterisk configuration as it differs from stock is below, with only one extension shown. Here's  sip.conf

[general]

register => BluefaceUser:BluefacePass at sip.blueface.ie/1000
udpbindaddr=0.0.0.0
allow=all

[1000]
type=friend
context=phones
host=dynamic
secret=seekr1t

[blueface]
type=peer
host=sip.blueface.ie
username=BluefaceUser
fromuser=BluefaceUser
secret=BluefacePass
insecure=invite 
context=incoming_calls

and here's extensions.conf

[globals]

[general]
autofallthrough=yes

[default]
exten => s,1,Verbose(1,Unrouted call handler)
exten => s,n,Answer()
exten => s,n,Wait(1)
exten => s,n,Playback(tt-weasels)
exten => s,n,Hangup()

[incoming_calls]
exten => 1001,1,NoOp()
exten => 1001,n,Dial(SIP/1001,30)
exten => _X.,1.NoOp()
exten => _X.,n,Dial(SIP/1001)

[outgoing_calls]
exten => _X.,1,NoOp()
exten => _X.,n,Dial(SIP/blueface/${EXTEN})

[internal]
exten => 500,1,Verbose(1,Echo test application)
exten => 500,n,Echo()
exten => 500,n,Hangup()

exten => 1000,1,Verbose(1,Extension 1000)
exten => 1000,n,Dial(SIP/1000,30)
exten => 1000,n,Hangup()

[phones]
include => internal
include => outgoing_calls

Any suggestions as to where to look would be greatly appreciated.
