[SR-Users] issues using evapi module

[David Escartin]

hello Daniel

i have tried the directive
listen=127.0.0.1:8448 and listen=tcp:127.0.0.1:8448
and i tried now  for example to connect with a tcp client from port 48583
(randomly selected when i made the tcp connect i guess)

tcp        0      0 127.0.0.1:8448          127.0.0.1:48583
ESTABLISHED 4508/kamailio        keepalive (2.24/0/0)

i configured the kernel to send keep alives 30secs after the tcp connection

should this be ok?

best regards
david
