canreinvite has been replaced by directmedia in chan_sip's config
file for at least a decade.  It has never existed for chan_pjsip.  For
chan_pjsip it is direct_media.

This section looks like you are trying to actually create the twilo
endpoint but
you need to include the twilo template you defined earlier: [twilo](twilo).
It would
be better if you actually gave the twilo template a different name.

You might want to look over config file common syntax [1] and template
usage [2].
You might also want to look over pjsip configuration [3].
