This is more just more to show little how I have configured my Asterisk set up and slimmed it down to use the minimal modules needed.
- SIP calls between my IP phone and Softphone
- Incoming/Outgoing calls through a SIP Provider
- Echo test to make sure audio is working
- Music On Hold (moh)
- Date and Time
- 12V fanless Mini ITX @ 533MHz (VIA Samuel 2) & 512MB RAM
- 10/100 Switch + WiFi AP
- Nortel 2002 IP Phone (NTDU91)
This is a channel driver for the UNISTIM (Unified Networks IP Stimulus) protocol. It provides UNISTIM server services that you can use to drive Nortel 2002 IP phone.
The following features are supported:
Message Waiting Indication (MWI)
Music On Hold
You might still have to pay royalty fees to the G.729 patent holders for using their algorithm
With Asterisk when you place a call or receive a call you’ll get a warning about translation from ulaw to g729.
[Dec 16 09:48:56] WARNING: channel.c:2811 set_format: Unable to find a codec translation path from ulaw to g729
With little googling I found out this is rather easy problem to fix.
Lots of caffeine
Long finger nails (they will be short by the end)
Needing a hair cut (might be bald by the end)
Note: I am just joking about the prerequisites, I found it hard to get stuff right cause a lot of howtos out there are bit vague and cryptic. So here is my attempt to make it a bit easier for others to setup Asterisk and connect to a VoIP provider.
