Dear All,

NEC SL1000 internal calls are not ringing to any analog extensions . i have total 12 analog extensions and 4 digital extensions are connected.
( 308 main board & a 008 expansion card) i can hear the ring back but any analog telephones are not ringing, but the sane time if i lift the receiver of the specific analog extension i can talk to the caller. ( eg:-- Analog extension 205 is calling to analog extension 208. no ring sound from analog extension 208 , if i lift the receiver i can hear 205. i checked the ringing volume also, it is normal. same for all analog extensions.)
digital extension users can talk each other , there is no ring issue.

please share any idea about this issue.
regards.

Check your ring signal voltage. Place a volt meter on T&R of a receiving station, then call it. You should get ~75-90 VAC. May be a bad PSW.

Thanks
