dexter gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/6320 increase RAN timeout in MGCP FSM The MGCP FSM implements a timeout when waiting for the RAN to complete the call (assignment complete, alerting, connect...). This timeout is currently set to 10sec. This means if the other end did not pick up after 10sec, the MGCP connection will be lost while the phone keeps ringing. When the other end finally picks up, the call gets disconnected. This behavior is odd and requires a proper fix. For now increasing the timeout to 120sec. will decrese the probability that he problem occurs. - Increas RAN timeout to 120sec (2 min).
