+SIP Changes
+-----------
+ * Added a new 'ignoresdpversion' option to sip.conf. When this is enabled
+ (either globally or for a specific peer), chan_sip will treat any SDP data
+ it receives as new data and update the media stream accordingly. By
+ default, Asterisk will only modify the media stream if the SDP session
+ version received is different from the current SDP session version. This
+ option is required to interoperate with devices that have non-standard SDP
+ session version implementations (observed with Microsoft OCS). This option
+ is disabled by default. In addition, this behavior is automatic when the SDP received
+ is in response to a T.38 re-INVITE that Asterisk initiated. In this situation,
+ since the call will fail if Asterisk does not process the incoming SDP, Asterisk
+ will accept the SDP even if the SDP version number is not properly incremented,
+ but will generate a warning in the log indicating that the SIP peer that sent
+ the SDP should have the 'ignoresdpversion' option set.
