Hi,
How am I expected to handle TLS when using TOPOS?
listen=tls:192.168.5.122:5061 advertise foobar.pbx.com:5061
modparam("topos", "storage", "db")
modparam("topos", "contact_host", “foobar.pbx.com")
modparam("topos", "dialog_expire", 10800)
When using TLS, TOPOS sets the contact header as something like this for a 200 OK returned.
Contact: <sip:[email protected]>
Is this valid? Or should it not be foobar.pbx.com:5061;transport=TLS
It appears some vendors blindly use the contact header and returns the ACK for an example to a non TLS endpoint, despite the dialog (INVITE) starting out as TLS.
