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.
Michael --Original Message Text--- From: hin lee Date: Sat, 30 Jan 2010 08:37:24 -0800 (PST) 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. http://www.trixbox.org/forums/vendor-forums-certified/polycom/increasing -speakerphone-tx-gain http://www.trixbox.org/forums/vendor-moderated-forums/polycom/430-sound- 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?

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? -- Michael Graves mgraves<at>mstvp.com http://www.mgraves.org o713-861-4005 c713-201-1262 sip:[email protected] skype mjgraves Twitter mjgraves
