Calls fail since v15 #376

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Since upgrading from v13 to v15 I have been unable to make calls through one of 
my PSTN gateway providers.  I've analyzed the SIP conversation and the problem 
is that CSipSimple is not authenticating when the SIP proxy challenges it for 
authentication.  Here is a transcript:

The last ACK message above is the last message CSipSimple sends.  In the UI it 
just hangs up after about a minute of doing nothing.  Here is a transcript of 
the same call with the same provider, but from a Nokia handset:

The call goes through with the Nokia handset.

What's strange is that CSipSimple doesn't have the same problem with Ekiga.net. 
 Here is a transcript between Ekiga and CSipSimple:

Thx for logs. I'm wondering if the fix I'm doing in issue 245 will not fix that 
one too.

Something about the difference between :
  To: <sip:0217903852@fnbconnect.co.za> (on your nokia)
&
  To: sip:0217903852@voice.fnbconnect.co.za (on CSipSimple)

The <> seems to impact the behavior of some sip servers.... I'll fix that in 
next dev build and only use <> instead of simple uri form.

I'll keep you in touch to test the new version, but the fix I'm doing can make 
sense to solve this problem.
