[Asterisk-Users] Cant receive calls after network goes down and up

[Steve Totaro]

You can change the setting.  I set mine for every 1 min on a small system.  The phones always work.
  What is the register interval in the grandstreams? The qualify=yes should keep the connection alive as long as Asterisk is up, but if it goes down and then comes back up, the phone has to re-register with Asterisk before asterisk can keep the connection alive.

  Hi,

   

  I have several Grandstream phones connected to Asterisk, some behind NAT and others not. If I reboot all the phones, everything is fine. Should the connection go down, and then come back again, those behind a NAT are still able to make calls, but are unable to receive calls.

   

      -- Executing Dial("SIP/1239-ba74", "SIP/1242|60|t") in new stack

  Jan 12 23:45:19 NOTICE[21576]: app_dial.c:803 dial_exec: Unable to create channel of type 'SIP' (cause 3)

    == Everyone is busy/congested at this time (1:0/1/0)

   

  However, extension 1242 is still able to call 1239? 

   

  Is this a configuration problem in Asterisk or in the phones?

   

  Please help

   

  Regards

   

  David Norton
