[edit] Session 2: End-nodes & Peers

Goal: Add more phones, of different type to the system, and connect to the other PBX-servers

1. Learn how linphone works on cabled PC-clients and make a test-call
2. Install linphone on portable wireless laptops and do the same
3. install linphone on handheld cellphones and make a test-call
4. Cisco IP Phones 7960:
   1. Setup the phone with IP address and TFTP location
      • Hit the Settings button a lot to access the setup-menu
      • If you can't access the menu: Do a factory-reset (power on w. #-key, 12345678*0#, yes) and hit menu button a lot
      • Choose Network setup and scroll down to option 30 (disable DHCP)
      • Choose Network setup and scroll down to option 8 (tftp-server) and set it to your trixbox-server IP-address
      • If you're still stuck; read this document
   2. Setup files
      • Make sure the phone looks for files by looking at the tftp-log, if it doesn't: go back to the previous point
      • Find the firmware files for that model (hard) Here
      • Edit some files to make sure it points to the correct version of your firmware
      • Run the linux-script setup-cisco
      • GUI: Create an extension for the IP phone; make sure NAT=no and Qualify=yes
      • Select PBX -> [Endpoint manager] and add the IP-phone and its mac address
5. Cisco IP Phones 7965:
   • Hit the Settings button a lot to access the setup-menu

   • Choose Network setup and disable DHCP
   • Change tftp-server to the IP of your trixbox-server
   • Make sure the right load information in XMLDefault.cnf.xml for 7965
   • Get the SEP{mac-address}.cnf.xml and make the changes needed in it

[edit] Session 3: Dial-Plan and Analog-Phone

1. Create a dial-plan to translate incoming 10-digit numbers to 4-digit extensions

   (i.e. Strip incoming numbers from 10-digits (0520-223202) to 4 digit extensions (3202) )

   1. Trunk: Add trunk
      To handle incoming 10-digit number you need to change in file /etc/asterisk/extensions_additional.conf (use GUI PBX->ConfigFileEditor ) and goto section ext-did-0001

      [ext-did-0001]

      exten => fax,1,Goto(ext-fax,in_fax,1)

      exten => _052269XXXX,1,Dial(SIP/${EXTEN:6})

      exten => _052269XXXX,n,Hangup()

       ;BEWARE!! -- Whenever you change and SAVE, this config *will* disapear

       ; end of [ext-did-0001]

      Probably better done somewhere else with a 052022 variable ... ??

   2. OUTGOING: Send numbers to correct PBX

      Add one trunk per other group (peer) by selecting "Trunks" in the GUI:

      TRUNKS

      Trunk Name: PODF

      [Peer Details]

      host=193.10.203.239

      type=friend

       ; !-- My own name -- must be same on other side's trunk name

      username=PODE

      fromuser=PODE

      secret=lol

      qualify=yes

      context=from-trunk

   3. OUTBOUND ROUTES

      [Dial Patterns] 052172XXXX

      [Trunk Sequence] SIP/PODF

2. Setup a sip-peer to the other PBX-server and create dial-plans accordingly
3. To Call Support between trunks
   1. Make a Ring-group
   2. Add all your extensions
   3. Make a SUPPORT extension
   4. Then Click "Edit Follow Me settings"
   5. Set Ring Time to 1
   6. Edit "Destination if no answer:" and select "call ring group"
   7. Whenever you call this extension it will go direct to "destionation if no answer" and call all extensions.

      ---

4. Configure the analog phone in AsteriskNOW

   ---

5. Överkurs: logga in på cellip.com MinaSidor, Din SIP-trunk har användarnamn 46520580026 och fixa så att det går att ringa ut

   Alternativt: fixa eget kontantkortskonto på phonzo.se och beställ Phonzo Cash (Kontantkort)
