Alpha: Google talk with PiaF

[Vik]

As a thank you to the Pbx in a flash team, i have put together a basic howto for googletalk and PiaF

If your PBX is behind a router, you need to forward TCP port 5222 to the asterisk server.

What is working:

Asterisk registers as a google talk client

It forwards incoming google talk calls to my SIP destination.

Calls from asterisk ring on Google Talk

For inbound calls, I can receive a message via google talk informing me of the Caller ID.

What doesn't work
The inbound and outbound audio - its just flaky and I haven't really had the time to trouble shoot.


Here are my configs

Jabber.conf

[general] 
debug=no 
autoprune=no 
autoregister=no 

[gtalk_account] 
type=client 
serverhost=talk.google.com 
username=email@gmail.com/Talk 
secret=*****
port=5222 
usetls=yes ; TLS is required by talk.google.com, you'll get a 'socket read error' without 
usesasl=yes 
buddy=buddy@gmail.com 
statusmessage="PiaF system" 
timeout=100

gtalk.conf

[general] 
context=google-in 
allowguest=yes 

                                                
; 
[guest] 
disallow=all 
allow=ulaw 
context=google-in 

[buddy] 
username=buddy@gmail.com 
disallow=all 
allow=ulaw 
context=google-in 
connection=gtalk_account

To make and receive calls, I have added the following lines extensions_custom.conf:

;[google-out] 
exten => 701,1,Dial(gtalk/gtalk_account/buddy@gmail.com) 

[google-in] 
exten => s,1,NoOp( Call from Gtalk ) 
exten => s,n,Set(CALLERID(name)="From Google Talk") 
exten => s,n,Dial(SIP/100) ; this can be a ringgroup or direct extension

To get notification of inbound calls, I have added the following line in my extensions_custom.conf

;Jabber Messaging
exten => 703,1,JABBERSend(gtalk_account,buddy@gmail.com,Inbound call from ${CALLERID(all)})

Then added 703# to all my follow me extensions. When a call comes in, I get a popup with the caller ID on my gtalk client.

As I stated earlier, this is a very basic approach to gtalk and asterisk interconnection. Please feel free to improve on this.

A big thanks to you! One of the reasons I released the installer was so some of the rabid experimenters could come up with the implementation onto PIAF. I hope some more of you contribute so I can adapt the configs above and include it into the install-gtalk program.

Did a fresh 1.3 install to upgrade from 1.1

Installed Gtalk via the script. All works great.

Found out that if you comment out:

;exten => s,n,Set(CALLERID(name)=”From Google Talk”)

in extensions_custom.conf

caller id will be the user's account info and will be in the CDR. Instead of it saying "From Google Talk" it will say "user's-id@gmail.com"

Most probably know this, but I thought I'd share with those who didn't.

I'd like to try this, but wondering if there are still audio problems...
