You talk about the virtues of Google Talk. But does it have the encryption found in Skype?

Adorah setup here is incomplete and I couldn’t figure out the problem… but here’s how to add IPKall as a Sip Trunk in FreePBX thanks to http://www.voip-info.org/wiki/view/IPKall

Settings for add Trunk in freepbx

1. click add sip trunk
2. leave everything blank except the following items

Outgoing Settings

Trunk Name: ipkall
Peer Details:

context=from-pstn
host=voiper.ipkall.com
type=peer

Incoming Settings

***** USER Context from-trunk *** I changed this to be able to use it without changing a thing… I changed from-external as the USER Context to the number I want to use in the Phone Number in IPKall

USER Context: 98765

USER Details:

allow=g729
context=from-trunk
disallow=all
dtmfmode=rfc2833
host=voiper.ipkall.com
insecure=very
type=peer

Now in IPKall I would use Phone Number 98765 server address mypbx.dyndns.org
My sip address in this example is 98765@mypbx.dyndns.org

Thanks for everything!

Thanks Ward for burning your midnight oil and telling us of this feature. Yes we too did the trunk setup like adorah above said. You always help us keep our bells ringing, to a different tone.

For some reason, I have only been able to get one way audio with IPKall. I have had this problem for years and have never been able to resolve the issue. The correct ports are open on my router. I can use other sip services. The only one that wont work is IPKall.

[WM: In your sip_custom.conf file, have you added the code below using the external ip and internal subnet for your network? Also be sure to read the new section in the article about Avoiding NAT Problems.]
[code]
externip=66.56.246.186
localnet=192.168.0.0/255.255.255.0
[/code]

You may configure IPKALL through FREEPBX by adding a SIP trunk.
simply fill in the incoming setting without registering:
USER CONTEXT: 588
type=peer
insecure=very
host=voiper.ipkall.com
dtmfmode=rfc2833
disallow=all
context=from-trunk
allow=g729 (or ulaw)
And that’s it. no need for user name or password..
One more thing: Dynamic DNS can also be obtained from http://www.no-ip.com, for free.
