Here is a working configuration for a Patton 4114 FXO running 5.4 where the ports are used for varying purposes (not just a simple milking machine setup).

Overview of setup

  1. FXO port 0 and 1 are connected to analog trunks on an ITSP's DTA (a grandstream). In this config I refer to them as 'PP'.
    1. Inbound calls
      1. Callerid is provided by the DTA Bell style
      2. Both ports ring for the same call if they are both free; there is a 1 ring delay on the 2nd port so both ports don't answer
      3. Inbound calls are directed to '0' (the AA) on sipXecs
    2. Outbound calls
      1. sipXecs is configured to see these two ports together as an unmanaged gateway on UDP port 5060
      2. Either port can be used to make outbound calls
      3. 1+10 digit dialing is used
  2. FXO port 2 is connected to a POTS Qwest line that does not provide callerid, QW is the abbreviation used for these elements
    1. Inbound calls
      1. Calls are directed to '0' (the AA) on sipXecs
      2. Callerid is fixed as Unknown, name 'Qwest'
    2. Outbound calls
      1. sipXecs is configured to see this port as an unmanaged gateway on UDP port 5061
  3. FXO port 3 is connected to a Viking W2000A-EWP doorphone, FD is the abbreviation for these elements
    1. Inbound calls
      1. Calls are directed to extension 224 on sipXecs (a hunt group)
      2. The callerid is set to number '250' name 'Front Door'
        1. Internally the hunt group goes to several Polycom 650's and 335's which are configured to issue a 'ding dong' distinctive ring on calls from '250' (via the speed dial RT feature and the SAF wave file feature).
      3. The input gain is pushed up by 6db as the doorphone's mic is pretty quiet
    2. Outbound calls
      1. sipXecs is configured to see this port as an unmanaged gateway on UDP port 5062
      2. The door phone does not provide dialtone, going off hook opens the intercom, there is some special setup in the config to deal with this
      3. sipXecs is configured with a custom dial rule just for this, when you dial '250' with '0' extra digits it sends a '1'. The patton is configured to strip the 1 out so you don't hear DTMF at the door when dialing out to it.

Patton plumbing

The Patton internally has a number of components you plumb up between the ethernet port and each FXO port. In some cases the same component is used for PSTN -> SIP calls and SIP -> PSTN calls. Below is a chart showing the high level plumbing (but not all the configuration details) for this configuration.
