[Kamailio-Users] Registrar: Save modified contact / set the qvalue

[Daniel-Constantin Mierla]

Hello,

for <= 1.5 is not easy to get to it, unless you use db mode only and 
play directly to database.

In 3.0+ you can change the contact header and then use msg_apply_changes():
http://kamailio.org/docs/modules/stable/modules_k/textops.html#id2749047

then do save to location.

Cheers,
Daniel
