+		Set the T1x64 timeout value used by the SIP transaction engine.
+		The T1x64 is duration used for timers B, F, H, and J (UDP) by the SIP transaction engine. 
+		The timeout value T1x64 can be adjusted separately from the initial retransmission interval T1. -->

+	<!-- Maximum retransmission interval (in milliseconds).
+		Set the maximum retransmission interval used by the SIP transaction engine. 
+		The T2 is the maximum duration used for the timers E (UDP) and G by the SIP transaction engine. 
+		Note that the timer A is not capped by T2. Retransmission interval of INVITE requests grows exponentially 
+		until the timer B fires.  -->
+	<!-- <param name="timer-T2" value="4000" /> -->
+		
+	<!--
+		Transaction lifetime (in milliseconds).
+		Set the lifetime for completed transactions used by the SIP transaction engine. 
+		A completed transaction is kept around for the duration of T4 in order to catch late responses. 
+		The T4 is the maximum duration for the messages to stay in the network and the duration of SIP timer K. -->
