+.TH GSM_PRINT 3 
+.SH NAME
+gsm_print \(em GSM\ 06.10 supplementary function for debugging
+.SH SYNOPSIS
+#include "gsm.h"
+#include <stdio.h>
+
+int gsm_print(f, g, frame);
+.br
+FILE * f;
+.br
+gsm    g;
+.br
+gsm_frame frame;
+.SH "DESCRIPTION"
+Gsm is an implementation of the final draft GSM 06.10
+standard for full-rate speech transcoding, a lossy
+speech compression algorithm.
+The compressed form involves 76 variables with different numbers
+of significant bits packed into 33 bytes.
+.PP
+If you are interested in investigating the details of this
+coding scheme, gsm_print() can be used to dump the contents
+of individual gsm_frames to a file pointer provided by
+the application.
+.PP
+.SH "RETURN VALUE"
+gsm_print() returns -1 if the frame is invalid, else 0.
+.SH EXAMPLE
+A single frame looks like this:

+/**
+ * simpleua.c
+ *
+ * This is a very simple SIP user agent complete with media. The user
+ * agent should do a proper SDP negotiation and start RTP media once
+ * SDP negotiation has completed.
+ *
+ * This program does not register to SIP server.
+ *
+ * Capabilities to be demonstrated here:
+ *  - Basic call
+ *  - Should support IPv6 (not tested)
+ *  - UDP transport at port 5060 (hard coded)
+ *  - RTP socket at port 4000 (hard coded)
+ *  - proper SDP negotiation
+ *  - PCMA/PCMU codec only.
+ *  - Audio/media to sound device.
+ *
+ *
+ * Usage:
+ *  - To make outgoing call, start simpleua with the URL of remote
+ *    destination to contact.
+ *    E.g.:
+ *	 simpleua sip:user@remote
+ *
+ *  - Incoming calls will automatically be answered with 180, then 200.
+ *
+ * This program does not disconnect call.
+ *
+ * This program will quit once it has completed a single call.
