FXO/FXS Audio problems

Hi,

I have implemented the following:

http://www.cisco.com/en/US/tech/tk1077/technologies_configuration_example09186a008009431b.shtml

inter-branch calls work 100%. Problem is that when remote site phones out (PSTN breakout at HQ) the audio is extremely soft. Any ideas?

Thnx

Charl

Re: FXO/FXS Audio problems

Have you tried adjusting gains and attenuation under voice port ?

Also very important, check you optimal impedance setting:
