#376 Calls fail since v15

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.
