Sometime ago i deployed CCME for one of our clients,there is a 2801 router with 8 PSTN lines terminated on 8 FXO ports,which then goes to a number of POE switches.
This set-up has been working okay,the problem is that the receptionist reports the whenever someone calls from the PSTN he/she hears multiple rings on their end,but the receptionist reports only get to hear 1 ring or sometimes the receptionist's phone does not ring at all-this is basically my problem.
The PSTN provider has done a number of tests and concluded that their side has n o problem.
The voice-ports/dial-peers are well configured,i have counter checked the configurations and they all seem okay.
Where could i be going wrong,
Please help,this client is on my case.
