Does anyone know how to enable the call waiting tone on an IP 450? I've looked through the phone menu and can't seem to find that settings anywhere.
welcome to the Polycom Community.
It is always useful to include the currently used SIP or UC Software version as issues experienced or a question asked may already be addressed in a newer release.
Please also include if you are using a SIP server or a LYNC server.
This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.
The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .
In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.
Therefore the Polycom VoIP FAQ contains this post here:
