tls usage requirements

[Luis Azedo]

Hi,

i can successfuly connect my spa504g to a kamailio server and get mwi notifications using UDP.

when i use tls, i successfuly register in the the server and also subscribe to mwi events.

i can make calls and srtp also works.

the problem is with kamailio server sending mwi notifications to spa504g when i use tls.

do i have to create a mini certificate and configure it in spa50g for tls mwi notifications to work ?

i don't know if the problm is with the server or with misconfiguration in spa504g.

the initial SUBSCRIBE event is successfulll and i can get a response (mwi light goes on if i have a vm).

the problem seems to be when the connection is initiated by the server.

any thoughts ? hints ?

thank you

Catch full log and debug messages

Debug and syslog Messages from the SPA3xx, SPA5xxG, SPA9xx, & WIP310 IP Phones

Just to be sure, catch the communication between exchange and phone as well (to verify that TLS is used all the times).
