[Freeswitch-users] Problem With TLS + Contact Header - Bug?

[António Silva]

Hi,

In the initial invite the contact header the tls part is missing:

    Contact: <sip:4640 at 4.3.2.1:5060>

it should have sips and transport=tls otherwise it will default to 
sip/udp, it's probably here the cause of your issue...

Since you have tls_only = true, FS shouldn't reply to the that contact 
or place a error message "wrong contact... or something"...
did you try with last git? can you try? and if it fails open a jira so 
the dev team can take a look.
