That 408 doesn't make sense to me.. If you got a 408 back, the gateway you are sending to WORKS, but IT'S destination is failing.
say for example you send to a gateway and that gateway sends to 10 different providers.. if this call routes to provider A, which doesn't respond, then your gateway may respond back with a 408. Where the failure isn't your gateway, it's your gateway's upstream.. -Brett On Wed, Feb 11, 2009 at 4:10 PM, Iñaki Baz Castillo <[email protected]> wrote: > I don't understand the following: > > > ----------------------------------------------- > ######################################################################## > ## Handles relay of INVITE messages > ## with round-robin load balancing > ######################################################################## > route[1]{ > ds_select_domain("1","4"); > t_on_reply("1"); > t_on_failure("1"); > t_relay(); > } > > [...] > > ####################################################################### > ## Handles failure of INVITE forwarding > ####################################################################### > failure_route[1]{ > xlog("L_INFO","Failure route, trying again\n"); > > if(t_check_status("408")){ > xlog("L_INFO","Got a 408 Timeout, flagging dest as > invalid\n"); > ds_mark_dst(); > route(1); > ---------------------------------------------- > > > In failure_route[1] you call route[1], and in route[1] you > execute "ds_select_domain()". > According to the doc: > http://www.opensips.org/html/docs/modules/devel/dispatcher.html#id271282 > "ds_select_domain()" can only be called from REQUEST_ROUTE, and not from > FAILURE_ROUTE. > I wonder why you don't get an error when starting your OpenSIPS. ¿? > > I expect you should use "ds_next_domain" in FAILURE_ROUTE: > http://www.opensips.org/html/docs/modules/devel/dispatcher.html#id271328 > > Are you 100% sure that this script works in your lab?
