You might use your own notification script, s.t. you can send a
Content-type: text/html for your E-Mail.

Hi Mark,

I guess there are incoming "lines" that send callerid rather reliably -
PSTN will most probably send the correct number, if it sends one. OTOH,
if you accept incoming SIP connections from unauthenticated hosts, they
could basically send any "from" phone number they wish. Your dialplan
should probably take care of that, possibly by prepending the callerid
with some prefix ("X_" or whatever). Your notification script could make
use of that information to _not_ provide a "callback link" in that case.

Several programs allow for special protocol handling; which mail
client/internet browser you use will determine wether you can configure
it to hand off "sip:" URIs to the proper program (X-Lite, a CTI
prog...).
