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).

2007/10/6, chen.liang.sip <[EMAIL PROTECTED]>:
hi,all
I've found following message from the mail list( ), i'd like to know if
anyone has successfully used http proxy in sofia sip stack?
I've tryed to use TPTAG_HTTP_CONNECT() tag in my program, when i filled one
string like TPTAG_HTTP_CONNECT("http://192.168.1.123:8080";) into the tag, which
means no authentication, everything looks fine, and sofia sip stack can use the
http proxy connect to the internet!
But when i filled the tag with TPTAG_HTTP_CONNECT("http://testaccount: [EMAIL
PROTECTED]:8080") , which using basic authentication, of course i've set basic
access authentication in http proxy, and i got the log message :
"
tport_http_connect: 407 Unauthorized
nta_agent: tport: 192.168.1.123:808: Protocol error
nta_agent: received garbage from TCP/x.x.x.x:5060/sip
"
And i also found in maillist that sofia-sip does not support NTLM
authentication at present, so i just want to test the basic authentication
method when using http proxy
Best regards,
Liang

this is not a very common feature in SIP stacks, but as it happens, Sofia-SIP
does support http-proxies. This is a fairly new feature though,so not widely
tested yet.You need to give the TPTAG_HTTP_CONNECT() tag, containing the
http-proxy
URL, to nua_create(). Sofia-SIP will then use HTTP's CONNECT method to open a
TCP socket that can be used for SIP signaling toward other SIP endpoints.Note
that the proxy needs to support CONNECT (RFC2817), and allow
connections to the SIP port (5060). Many http-proxies are configured to only
allow connections to ports 80 and 443. Of course, you could set up a SIP server
listening on port 443... :)
