[asterisk-users] microphone on Polycom 550/650

[Michael Graves]

There's no issue here. There are parameters in the Polycom config files
for the various gain settings. The headset, handset and speakerphone
volume and mic gains are all separate. They can be tweaked as you like
via the config files.

Yes, the external calls are going over DAHDI.  The problem is on the
Polycom phones b/c if I pick up the handset, the other end can hear me
fine.  The problem is when using the hands-free (speakerphone) instead
the handset.  

Here are some similar posting of the sa
issue.

volume-gain

Most of our phones are IP 550.  Where and what do I need to adjust the
setting to fix this issue?  Any Polycom experts in this mailing list?

You don’t state this, but the assumption would be that your external
calls are DAHDI based, so you might need to tweak txgain in dahdi.conf.

I have quite a number of users complaining that when they are using
handsfree to talk over a landline, the other end can't hear them.  It's
like the person is speaking 5 feet away and can barely hear their
voice.  However between internal SIP calls, it's fine.

What could be the problem?
