[SR-Users] Reactivating a failed dispatcher destination

Fri May 20 11:27:17 CEST 2011

OK, I will see what I can do at my end but it's odd that when the ping first kicks off a 481 is sent back but the server stays listed as active.

Thanks for the help.

Regards

Lee

Hi,

i think i added the feature in 3.1 to configure the valid responses.
In prior versions, only the following reply codes are considered a "valid" reply:
- 200 OK
- 501: Cisco-Gateways reply with a "501 Not supported" to the request.
- 403: Aastra-Gateways reply with a "403" to the request.
- 405: Some GWs reply with a "405 Method Not Allowed" to the request. */ and it is hardcoded in the module....
So that is why your setup does not work.
