Hi, as you are using Asterisk 13 with libss7 it is highly recommended to enable all the timers not just mtp3_timer.t21 (from your other post). To enable timers you need to explicitly define them or simply "#include ss7.timers" (provided with samples) for each and every linkset The sample config (ss7.timers) provides the default values for the timers, you may change them, but by setting mtp3_timer.t21=1 you are begging for other problems later.
