Hi Gang
Next question.
I have some broken CPE which do not set a=ptime despite using 20ms which then causes the call to get rejected in certain destinations, because ptime header is missing.
So I would like to match the user-agents in question and add back a=ptime:20
Google searches found an user with the exact same problem almost 10 years ago and Daniel replying that indeed a function to add a body line would be handy.

How could this be accomplished? I don't see a add_body_line or other function which does not 'replace' a body line.
