New subject: dispatcher - ds_mark_dst("i"); is inactive only few seconds

2 Feb 2011


      Dear sr-users,
I use this straight forward dispatcher config.  In the failure route I am calling this function: ds_mark_dst("i");
Also this action is logged:
Feb 2 17:20:31 node5 /openser/sbin/kamailio[15945]: INFO: : FAIL_ONE:time [Wed Feb 2 17:20:31 2011] destination sip:10.12.19.31:5060 marked as inactive
The gateway is inactive:
[root@node5 ~]# kamctl 'fifo' ds_list
URI:: sip:10.12.19.31:5060 flag=I priority=0 attrs=test1=123;test2=456
URI:: sip:10.12.19.21:5060 flag=A priority=0 attrs=test1=123;test2=456
Few seconds later the gateway is active again (there is still now response to SIP-OPTIONS)
[root@node5 ~]# kamctl 'fifo' ds_list
URI:: sip:10.12.19.31:5060 flag=A priority=0 attrs=test1=123;test2=456
URI:: sip:10.12.19.21:5060 flag=A priority=0 attrs=test1=123;test2=456
Does anybody have a idea why ?
regards,
Thomas
