There is no authentication supported there.
I guess it would be relatively easy to Basic authentication if you had
username/password in the proxy URI, like TPTAG_HTTP_CONNECT("
Http://user:[EMAIL PROTECTED]:8080"). Have a peek in
libsofia-sip-ua/tport/tport_type_connect.c. You need to add a
Proxy-Authorization header with the username and password encoded in base64
(see RFC2617 and sofia-sip-ua/ipt/sofia-sip/base64.h for details).
