I hear you... you're not the first person that's told me that. It's one 
of the top reasons I hear for staying on chan_sip.
Unfortunately, the author of those patches hasn't expressed interest in 
porting the functionality to PJSIP due to some misconceptions about 
PJSIP development. Some of it I might take a stab at to allow some of my 
users to move over, but not until outstanding patches have cleared; I 
have some of these phones but don't really use them, so it's lower on my 
priority list.
