[OpenSIPS-Users] TLS issue

[Bogdan-Andrei Iancu]

Hi MAtt,

HAve you tried to see if the TLS devices (1) are able to reconnect to 
OpenSIPS and (2) send SIP traffic to OpenSIPS after such no-Internet 
event ? Maybe you can use the siptrace module to try to capture the SIP 
traffic sent to OpenSIPS via TLS.
