I have an Asterisk from source system running fine. Inbound and outbound calls from internal SIP phones/extensions through X100P card work great - when the card is connected to a standard CO trunk or to a particular phone switch.
But if I use a Skutch line simulator to simulate inbound calls/rings - Asterisk/X100P doesn’t see the ringing.
Asterisk does see the presence of the loop current from the Skutch because I get:
Apr 21 19:46:20 WARNING[9141]: chan_zap.c:5652 handle_init_event: Detected alarm on channel 1: Red Alarm
Apr 21 19:46:21 NOTICE[9141]: chan_zap.c:5647 handle_init_event: Alarm cleared on channel 1
If I unplug the line.
I’ve looked over the parameters in ZAPATA.CONF and haven’t found anything that I thought would fix the problem. I am running in Kewl Start mode. I tried Loop Start and that didn’t work either.
I thought maybe I could add a custom ring cadence - but I wasn’t sure if that was for inbound or outbound rings. I also think the Skutch ring is pretty standard. I also thought about adjusting rx/txgain - but didn’t know what direction to go.
I think I just need to make the X100P more sensitive to rings.
Any thoughts?
