SPA3102 Incoming PSTN call fails after one ring

Discussion in 'Help' started by ukiechris, Apr 21, 2011.

    I have a brand new install of PBX in a Flash.

    Have a VoIP trunk set-up (voip.ms) and the incoming calls go flawlessly to the designated ring group.

    I set up another trunk (PSTN) according to this guide:

    Outgoing calls go through without a problem.

    When I place an incoming call, I hear one ring on the phone placing the call (cell) and one ring on the receiving device (Aastra55i), after which the call is disconnected: ringing tone changes to busy tone on the cell phone, and the receiving device stops ringing.

    I have successfully set this us in trixbox at a different location using the same guide.

    Any suggestions?

    Inbound context (I think) is wrong. For incoming PSTN calls context should be "from-pstn" (without quotes)

    *edit* What you describe is what happens if you have the wrong context, but the "from-trunk" should work, so I'm not sure what the problem is. Dial in and send us a snippet of the full asterisk log.

    If it worked with trixbox, it will definitely work with PIAF (only better!).

    In addition to what lgaetz suggests, re-check where your "PSTN Caller Default DP" is pointing to, on the "PSTN Line" page. The Dial Plan it references should look something like (S0<:s@>), only the actual IP address should be of your PIAF box, not the one illustrated.

    The ":5060" part may or may not be required, but I've always included the port reference.
