VVX300 (v. 22.214.171.12425) works fine when answering incoming calls until I add the VVX Expansion module. With the expansion module attached when a incoming call is received it no longer shows an external caller id instead shows a different extension number. When I go to answer the incoming call it gives me a new Outgoing dial tone instead of picking up the Incoming call.
Have 6 phones in a ring group including the one with the Expansion Module. All Phones ring at same time. Using the VVX Expansion Module for BLF/Transfer for 12 phones.
welcome to the Polycom Community.
It is always useful to include the currently used 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:
