Voice level issues with VCX connected to analog lines

Hi There,

 

Are there any particular parameters available that you can verify with the telco to ensure their analog lines meet the particular standard for the VCX FXo gateway to avvoid volume and voice quality issues?

Re: Voice level issues with VCX connected to analog lines

These are your telco specifications for everyone to adhere to .:

 

Std analog integration on an analog line ( FXO type )

PBX'es are -24 volts as they don't need the full -48 volts .

 

-48 Volts Dc

25 to 35 Milliamps

ring voltage = 105 Volts AC standard ringing .
