Apologies for the late response but I am just catching up with some old
mythtv-users mail. I read this thread and got interested. I do see that
others have provided nice solutions via the telnet interface but when
you mentioned "home-grown application" I wondered -- are you not using
mythtvosd? mythtvosd does the UDP broadcasting, and the frontend already
has a listener for the type of traffic generated by mythtvosd. Your
"home-grown application" seems to be duplicating this functionality.

Here's what I have set up for this in my Asterisk server:

----------------------------------------------------------------------
exten => s,1,NoOp(Start s)

; Send CallerID information to MythTV frontends
exten => s,n,System(/usr/local/bin/mythtvosd --template=cid --caller_name="${CALLERID(name)}" --caller_number="${CALLERID(num)}" --caller_date="${STRFTIME(${EPOCH},,%x)}" --caller_time="${STRFTIME(${EPOCH},,%X)}")
----------------------------------------------------------------------

The only problem with this is that this only works during playback,
and if the frontend is doing something else no CallerID information is
displayed, which leads to Wayne's reply in this thread:

This is nice. I'll give XOSD/osd_cat a try.
