I’m running FreePBX and sometimes need a telephone number for a special project. IPKall fits in perfectly.

Free Washington state phone number to your Internet phone.

Welcome to IPKall, the service that lets you receive FREE calls over the Internet from any phone, anywhere, any time!

FREE IP Calling with IPKall.

Here’s how I setup my FreePBX system:
1. Go to www.ipkall.com and sign up for a free number. Select/Use the following on the signup page:

Account type: IAX
User Name: <the 10 digit ipkall telephone number>
Proxy: <the IP or hostname of your freepbx server>/<the 10 digit ipkall telephone number>

Example:
User Name: 3065551212
Proxy: pbx1.mydomain.com/3065551212

2. On your freePBX server, create a new IAX trunk and use the following information. (Everything else can be left alone.)

TRUNK NAME:IPKALL
USER CONTEXT: <the 10 digit ipkall telephone number>
Remove the Secret line from the USER Details area.

3. On your freePBX server, create a new Inbound Route and use the following information. (Everything else can be left alone.)

Description: IPKALL
DID Number: <the 10 digit ipkall telephone number>
Set Destination: <Indicate where this DID should terminate>

4. Save and update the FreePBX configuration.

I just discovered Elastix, It is an ISO image that installs CentOS, Asterisk, FreePBX, and other goodies to create an instant PBX. Compare it to PBX In A Flash and Trixbox.

I was looking for a small, lite weight software based phone for my Windows laptop that would connect back to my Asterisk PBX using the IAX protocol. iaxLite is perfect and works great. I haven’t tried sipLite (same phone but uses theSIP protocol) yet. Well worth a look if you are using Windows.

iaxLite is a IAX2 softphone. sipLite is a SIP softphone
