Hello everybody
i have 12 fxo ports which connect to PSTN with my 2801 router and PVDM2-16
and i have CUCM7.1 which is my Call Processing server
my problem is somtimes oitgoing calls through FXOs have problem, for example they have echo, delay and a major problem is both side of the phone line could not speak at same time and call getting beaked until one side stop talking.
does anybody have any of this problem
here is my FXO ports config
voice-port 0/0/0
trunk-group FXOPORTS
supervisory disconnect dualtone pre-connect
supervisory answer dualtone
input gain 14
timeouts call-disconnect 0
timeouts wait-release 1
connection plar opx 899

voice-port 0/0/1
trunk-group FXOPORTS
connection plar 700
caller-id enable

Try removing the 'input gain 14', resetting the voice port (shutdown, no shutdown) and see if the issue improves.

Dear Jonathan
thank for your replay

today i'm thinking about the change the signaling from Loopstart to Ground Start, whats your opinion?? is it useful or no?

No, with groundstart it would not work at all.
You should configure cptone
