<add an inbound rule as follows: Disposition: Pass,
SP: 5060, DP: 5060, stateful is enabled>
This new rule will allow SIP calls to be initiated from
the inbound direction.
Inbound PT: UDP, SA: 10.10.10.2, SP: 5060, DA:
10.10.10.1, DP: 5060
No stateful session with [UDP, 10.10.10.1,
10.10.10.3, 5060, 5060] is found. An inbound user
rule is found and stateful is enabled. A new stateful
session is created with a disposition to “pass” only
(but not to mark].
Now SIP calls can be completed.
