As stated in the subject, slightly off-topic, as it is not directly a
Asterisk issue, but more SIP in general
Because security in general, and specifically identification becomes
more and more a subject for more concern, and Asterisk is capable of
doing sip/TLS, i was wondering what more could be done to improve
Specially softphones, might it be possible to employ etokens or
smartcards for holding the certificates needed by TLS?
