[asterisk-users] Newbie Polycom: IP600 Headset Problem

[Lee, John (Sydney)]

I have been testing with Polycom IP600 phones for a month or so.
I found out that there are frequent problems with the handset.
The problem is I can hear the other end but the other end cannot hear
me.

I have already downloaded the latest bootROM 3.1.3 and sip 2.1.2

However, there are no problems with the headset or speaker phone.

Has anyone encountered such problems before?

Thanks.
