update default value for NAT option in sip.conf
in Asterisk's sip.conf.sample:
; nat = no ; Do no special NAT handling other than RFC3581 ; nat = force_rport ; Pretend there was an rport parameter even if there wasn't ; nat = comedia ; Send media to the port Asterisk received it from regardless ; ; of where the SDP says to send it. ; nat = auto_force_rport ; Set the force_rport option if Asterisk detects NAT (default) ; nat = auto_comedia ; Set the comedia option if Asterisk detects NAT
Previous Wazo default was no, new default is auth_force_rport.
