    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
      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:
      Trunk Name: PODF
      [Peer Details]
       ; !-- My own name -- must be same on other side's trunk name
      [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

    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.
