I have an analogue phone connected to the the FXS-port of a TDM400P clone, which works, but with a small glitch:
When I switch off (On Hook) the phone to end an active phone call, I have to wait 2-3 seconds before switching it on again (Off Hook) to make another call.
Other wise (fast On Hook/Off Hook), I see the following in the asterisk CLI:
…
– Hungup ‘ZAP/1-1’ (My telephone)
Warning[2799]: chan_zap.c:1625 zt_set_hook zt_hook failed: Device or resource busy
On my telephone, in this case I do not receive a dial tone, untill I switch if off (On Hook) again.
It looks like some kind of race-condition to me, the Hung-up is detected, but not processed before the off-hook again.
Any ideas ?
