I had seen several inquiries regarding the message waiting reminder beep on Polycom phones. since I do not use voicemail myself on my Polycom it did not affect me. But I have since had several customers complain about it, inlcuding my boss this week. I figured there would be a flag somewhere to turn this on/off but was unable to locate one. So I did the next thing and changed the beep to be silence. perhaps someone has a more straightforward method but his works easily. In your sip.cfg file replace <MESSAGE_WAITING se.pat.misc.1.name="message waiting" se.pat.misc. 1.inst.1.type="chord" se.pat.misc.1.inst.1.value="1" se.pat.misc. 1.inst.2.type="chord" se.pat.misc.1.inst.2.value="2" se.pat.misc. 1.inst.3.type="chord" se.pat.misc.1.inst.3.value="1"/> with <MESSAGE_WAITING se.pat.misc.1.name="message waiting" se.pat.misc. 1.inst.1.type="silence" se.pat.misc.1.inst.1.value="1"/> and enjoy the peace and quiet, the light will still light, stutter will still work, just will not give the internittant beep.
