That lok sindeed very strange. HAve you tried other TLS clients (SNOM,
eyebeam, minisip)?

Hi all,
I'm posting this again due to lack of response. If this is the wrong forum for
this kind of query, please could someone let me know of a list that would be
more appropriate. After further investigation and successful testing against
other UAs I am less inclined to believe that the problem lies with our TLS
implementation, rather that the problem lies with OpenSER.

Subject: Error parsing URI's using TLS
Hi all,
I've just started using OpenSER to test our SIP implementation and have
encountered a problem with TLS early on. I can register with the server without
any problem but my calls fail. The logging from the server shows:

This would suggest that my (for example) From header contains a URI of: <sip:>!
Not overly useful you might say. Now, the same INVITE without encryption works fine
with OpenSER (using either TCP or UDP) and a serialisation of the INVITE immediately
before encryption (shown below) shows the correct URIs in all the right places.

For the moment I am pretty much assuming that this is a problem with our implementation as it is still under development but I can't work out what.
2 questions:
1. Does anyone have any general thoughts as to what might be going wrong?
2. Is it possible to get more logging from OpenSER that might shed some light?
