-Comments on IETF ICE compliance
-------------------------------
-
-Telepathy frameworks streamed media support was first implemented for
-Jabber/Jingle ICE-RTP profile. Using the same interface for SIP based
-media session setup creates some challenges (most urgent first):
-
-Spec issues
-~~~~~~~~~~~
-
-- some differences in terms: IETF-ICE has component (candidate-id) and transport
-  identifiers (tid) and a session-level password (ice-pwd), which are similar but 
-  not equivalent to Telepathy transport properties 'user' and 'pass'
-- the candidate-id values should be random with length of at least 
-  four characters
-- libjingle does not support multiple components (like one for RTP and one
-  for RTCP) per candidate
-
-Implementation issues
-~~~~~~~~~~~~~~~~~~~~~ 
-
-- open: to talk with non-ICE compliant SIP endpoints, libjingle has to
-  support bypassing connectivity checks for the default candidate - can
-  this be done?
-- currently libjingle does not emit NativeCandidatePrepared, making it 
-  more difficult to decide when to send all local candidates (whether to
-  wait until one of each type of candidates is generated, or some fixed
-  time interval?)
+the "--enable-debug" option, which is on by default.
+
+Other useful environment variables:
+* TPSIP_DEBUG -- enables debug tracing via g_log.
+  The value "all" enables all categories; for detailed categories look into
+  the file 'src/debug.c'.
+* TPORT_LOG -- setting to 1 enables logging of SIP protocol messages.
+
+See also Sofia-SIP documentation for environment variables to enable tracing
+in various modules of the Sofia-SIP library:
