Hello, I'm testing gateways failover with several gateway for bridge AND ping setting. It works but INVITE timeout and SIP Options timeout is quite long (32 seconds) because of timer-T1X64 setting (it's what i hav readen) I would like to modify timer-T1X64, for example : 3000. Invite failover would and SIP option timout would now be : 3 seconds. Tests are OK, Invite failover and gateway marked down is very quick. My question : is there any impact on behavior of other transactions in SIP protocol ? Is there no risk to reduce timer-T1X64 from 32000 to 3000 ? Thanks, Best regards, Marc
