Subject: [PATCH] res_pjsip_session: Deferred re-INVITE without SDP send
a=sendrecv instead of a=sendonly
Building on ASTERISK-25854. When the device requests hold by sending SDP with attribute recvonly, asterisk places the session in sendonly mode. When the device later requests to resume the call by using a re-INVITE excluding SDP, asterisk needs to change the sendonly mode to sendrecv again.
