To-Do

• Get Callcentric DID (or Other)
• Edit Sip.conf and Extension.conf With Callcentric login and a Google account
• Test (DTMF TONES, calling, Dialplan, other)
• Change Voicemail Settings (send wav to someone)

Prerequisites

Supplies

• Sip Phone (cisco sip)
• Debian Server
• Callcentric DID
• Google Voice account
• Python 2.7 w/ setuptools and simplejson
• pygooglevoice script
• tftp (phone config)
• apache2 (host directory and logo)

What was installed

• python-setuptools
• pygooglevoice script
• tftp
• apache2
• asterisk 13

Installing Pygooglevoice

• We Ran the below code at root mainly to insure the install of pygooglevoice-0.5.tar.gz

wget http://pygooglevoice.googlecode.com/files/pygooglevoice-0.5.tar.gz
tar zxvf pygooglevoice-0.5.tar.gz
cd pygooglevoice-0.5
python setup.py install
sed -i 's|https://www.google.com/accounts/ServiceLoginAuth?service=grandcentral%7Chttps://accounts.google.com/ServiceLogin?service=grandcentral\&continue=https://www.google.com/voice%7C' /usr/local/lib/python2.7/dist-packages/googlevoice/settings.py

sed -i 's| galx.*| galx = re.search(r\"name=\\"GALX\\" type=\\"hidden\\"\\

*value=\\"(.+)\\"\", content).group(1)|' /usr/local/lib/python2.7/dist-packages/googlevoice/voice.py 

• Latter We installed asterisk 13 from source and Apache+php using the Package manager as well as the tftp server we decided on using.

Main Files

TFTP

The Main files here are:

• dialplan.xml = dialplan on Phone ONLY
• P0S3-08-12-00.load = Phone Firmware
• XMLDefault.cnf.xml = All Cisco Phone config
• SIP(MAC_HERE).CNF = Phone config
• SipDEFAULT.CNF = All Cisco SIP Phones config
• *.PCM and *.RAW are ringtones (config-ed in RINGLIST.DAT)

HTTP

• NOTE: HTTP on cisco requires port usage in urls it will not assume port 80
• The Directory is located here! and the directory is a simple XML file (freeside.php with xml headers) ever there is a limit of 32 entries be warned If we need more we will need to use a database and fetch from there using a different script
• the Phone logo I also here

Asterisk Setup

We edited sip.conf and extensions.conf to our info. Adding a password to the phone and the correct Callcentric and Google info. Note: after editing the documents you must restart asterisk. After the asterisk server was up we set up the TFTP server with the config files for the phone and the ringtones.. the config file had to be added to to include the network IP of the TFTP server, the web-server and asterisk install and the creds. we gave this user in sip.conf
