Hi Guys,

I have been running a Asterisk PBX box at home for a while now. A bit of fun, and cheap toll calls with a SIP provider in the states.

In the weekend I found an old motorloa modem that has telepermit I that I was going to use for PSTN calls.
I can make calls out, and receive calls, but the modem will not hang up.

I have been into asterisk and looked for NZ cadences/signaling rules, but there is none.
Zaptel etc have aus, us, and a lot more. But no NZ.

Has any one in NZ used asterisk over PSTN?

Welcome you comments

Cheers

Hmmm. I am interested to know about this. Is there an Asterisk version for Windows? Does it require a special modem or any voice modem will work with it? Will it work on Windows XP?

There is a windows version of Asterisk. have not used it yet.
You need a special modem with the right Ambient or Motorola chipset onboard. There are also an ISDN cards that works with Asterisk that is in PTC with Telecom at the moment.

Have a look at this.

You're the first person I've ever come across who has actually tried one of the Moto modems with Asterisk and got it working! I've just stuck with Sipura 3000's as they are a much nicer unit! :-)

In regards to signalling there are issues with handups with most FXO cards as well. I'm on my way out now so will send you some NZ specific stuff later. You may also have to ring Telecom and get a setting changed on your line to get hangups to work correctly.

NZ indications are as follows (courtesy of www.sineapps.com - NZ based Asterisk developers)

[nz]
description = New Zealand
ring cadence = 400,200,400,2000
dial = 400
busy = 400/375,0/375
ring = 400+450/400,0/200,400+450/400,0/2000
congestion = 400/375,0/375
callwaiting = 400/200,0/3000
; Making this up
dialrecall = !425+25/100!0/100,!425+25/100,!0/100,!425+25/100,!0/100,425+25
; Making this up
record = 1400/425,0/14525
; Making this up
info = 400/2500,0/500

Also check out this page for some help - it also refers to ringing Telecom NZ. I have not actually needed to do this as I gave up on my cheap X100 card after I realised it was crap and have had no issues with call disconnects using the SPA3000.

If you want to have a play you can install VMware player and then install the Asterisk@Home VM file. You can't access a phyisical FXO ard under windows but something like a Sipura 3000 can be as it's ax external SIP device connected via the network.

There are no "true" Windows ports, they all run using cygroot or vmware.

Hmmm. I use Virtual Server here, and I thought the VM files were compatible. I will have a look for some information, and if it works I will try.

But I am really interested in testing this...

The New Zealand indications have been in the zaptel drivers for some time. The indications don't have anything to do with disconnect supervision though.

There are two ways for Asterisk to detect far end disconnects;

1) detecting busy tones - this is done with the busydetect option in zapata.conf.
2) detecting signalling on the line - for this in NZ you will want to use kewlstart signalling (fxsks) which you can specify in zaptel.conf and zapata.conf.

The second option is the preferred one but to use it you will need to make sure that Telecom is sending the signalling down the wire.

There is some more talk about it at the NZ Asterisk Users Group here;
