Most of the time my phone line are working OK but at time to time when I run:
asterisk -rx “core show channels” it show:
Channel Location State Application(Data)
SIP/pstn-4444-000000 (None) Up AppDial((Outgoing Line)) SIP/pstn-9998-000000 7807586576@internal: Up Dial(SIP/97807807586576@pstn-4
2 active channels
1 active call
even though nobody is using any line. I’m using Audiocodes gateway.
Does it have anything to do with “disconnect supervision” on analog line in Audiocodes gateway?
