  * Send a request within a dialog

+ * 

+ * Some parameters are required, some are optional (i.e., ephemeral

+ * or default values are created if 0 is passed as parameter). The

+ * optional parameters are typically used to set some header fields

+ * to dialog-related values (as opposed to having them set to

+ * ephemeral values).

+ *

+ * Required:

+ * - msg ..   specifies type of message, such as "OPTIONS"

+ * - ruri ..  specifies request URI; 

+ * - from ..  value of From header field (if it already includes from tag, 

+ *            the fromtag parameter MUST point to en empty string)

+ * - to ...   value of To header field (if it already includes to tag,

+ *            the totag parameter MUST point to an empty string)

+ * - totag .. to tag

+ * 

+ * Optional:

+ * - dst     transport destination (expressed as URI) -- if present,

+ *           request is physically forwarded to address indicated in it,

+ *           overriding the transport address in ruri; useful for use with 

+ *           outbound proxies or loose routers (that is where the first 

+ *           element of route set comes in)

+ * - fromtag from HF tag -- dialog-less applications do not to set it (==0),

+ *           in which case an ephemeral value is created; if fromtag present,

+ *           its appended to the From header field; it may be also present 

+ *           and point to an empty string -- that only makes sense if

+ *           application includes the tag in From and does not care to

+ *           separate the tag from the rest of header field

+ * - cid ..  callid; if 0, ephemeral value is created; transactions

+ *           within a dialog need to set this value to dialog's callid

+ * - cseq .. CSeq; if 0, default value (DEFAULT_CSEQ) is used; transactions

+ *           within a dialog need to set this value to current local cseq,

+ *           which grows continously with transactions sent

+ * - headers .. block of header fields that will be included in the

+ *           message. It MAY NOT include header fields already described

+ *           in other parameters (From, to, cid, cseq) or created 

+ *           automatically   (Content_length)   otherwise the parameter

+ *           would appear multiple times. It MUST include all additional

+ *           header fields required for a given SIP message, like Content-Type 

+ *           for any messages including a body or Contact for INVITEs.

+ * - body .. if present, body and Content-Length is appended to the 

+ *           SIP message; Content-Type then needs to be present inside

+ *           'headers' parameter

+ * - cb ..   callback to be called when transaction completes; if none

+ *           present, no callback will be called

+ * - cbp ..  callback parameter -- value passed to callback function

+ *           when called
