[OpenSER-Users] dispatcher and auto reload of previously failed GWs

[Miroslav HOSTINSKY]

Hello,

  ehm... I would like to have the following scenario working:

  1. dispatcher load-balance between SIP GWs (based on call-id)
  2. one GW fails -> dispatcher detects it and remove from list
  3. dispatcher starts to ping (with OPTIONS) failed GW until
     failed GW is back online.
  4. when GW is online, despatcher "reloads" back previously
     failed GW to balancing list...

I was not able to get working steps 3. and 4.

Recently I found solution:

  I replaced ds_mark_dst(); with ds_mark_dst("p");
  and it works :)

Thank you :-)
