### Description

Let's assume we have a MO call from UE to P-CSCF that's over ipsec. Let's 
assume the picked ports are like UE(6101) -> P-CSCF(6100)
We have also set tcp_connection_lifetime to be 20 sec.
20 sec after INVITE connection is RST from Kamailio as expected.
Then ( > 20sec later) an INVITE response comes from B side, and must be 
delivered to the UE.
Kamailio opens a new connection and tries to establish a connection from 5060 
(standard port)->6101 instead of 6100(P-CSCF) -> 6101(UE). IPSEC associations 
are not engaged and UE does not handle the request properly. 


### Troubleshooting

#### Reproduction

#### Debugging Data


#### Log Messages


#### SIP Traffic

### Possible Solutions
The IPSEC module should re-open the tcp connection if it sees it's been dropped 
as core module has no awareness of IPSEC.
