I've got phantom calls ringing one of the two IP331s my company purchased and I was wondering if there were any sort of filtering options for incoming calls to validate them?
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.
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:
