[asterisk-users] microphone on Polycom 550/650

[hin lee]

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 same issue.

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?
