+------------------
+ * Added "ignore_uri_user_options" global configuration option for
+ compatibility with an ITSP that sends URI user field options. When enabled
+ the user field is truncated at the first semicolon.
+ Example:
+ URI: "sip:1235557890;phone-context=national@x.x.x.x;user=phone"
+ The user field is "1235557890;phone-context=national"
+ Which is truncated to this: "1235557890"
+
+ Note: The caller-id and redirecting number strings obtained from incoming
+ SIP URI user fields are now always truncated at the first semicolon.
