How to Troubleshoot Low Volume In Conference Calls

Unanswered Question
Jul 20th, 2009

Hello,

I have been told on numberous occasions that when I setup a 3 party conference call, that neither party can hear each other. The volume is very very low for them. As the person that has setup the conference call, they can however hear me just fine.

I have MeetMe conferencing enabled but I am just using the 3 way conferencing in this case.

When I establish a meet-me conferencing bridge, the volumes for all the parties are fine.

Please advise.

Thanks

I have this problem too.

Yes,

It is all PSTN. We are utilizing 4 pstn lines here with the UC. I'm not sure what the other parties are using though.

I will look over the document that you posted. Thanks.

Marcos,

I looked through the article you posted and I have fooled around with PSTN levels before on this system. Raising them more than just a couple notches higher than the default produces not so desirable audio on voice calls. Static and the audio sometimes cuts out.

I wound up just setting it back to the default settings for gain and attenuation.

Is the DSP hardware used for making these types of conference calls or is it done at a software level?
