Summary:                    [patch] Asterisk is using wrong clock frequency in
text T140
Description: 
Timestamp in text T140 (RFC 4103) is wrong. Asterisk transmits it with a
clock that runs 90000 ticks per second. In the SDP Asterisk declares that
it uses 1000 ticks per second.

The problem originates from function ast_rtp_raw_write in rtp.c. The clock
frequency for text is set to 90000 instead of 1000.
Probably this lines need to be changed and predictioncode for text needs
to be removed:
"rtp->lastts = rtp->lastts + ms * 90;"

Edit: (inline patch removed by blitzrage)
