SD 9200 - SA ping-mode @ trans-timeouts

Hello,

i am using SD 9200 7.0.0m10p2 and i can not find ping-mode parametr on the SA level (according to BCP. Also, in case that SA pinging is disabled: ping-method none , ping-interval 0, the option trans-timeouts=3 does not work. I supose that if i disable pinging and set trans-timeouts=3, SBC will send 3 non-pinging transactions (for example INVITE) to SA and if SA will not reply, SBC mark this SA as Out-Of-Service. My questions are:

 

1. Is neccessary to set some another parametrs to enable trans-timeouts than these?

ping-method none

ping-interval 0

options trans-timeouts=3

 

2. Is there any configurable tmeout (in case that options trans-timeouts=3 is configured) when SA will be marked back as In-Service? Is it
