I am trying to add a shared line to an IP 335 phone. The phone is connected to an NEC SV8100 PBX. The 2nd line is assigned to an NEC 12 button IP Phone. If I assign the numbwer to the 335 then it takes over and line 1 does not work. I am not sure if I have a Polycom or NEC issue.
welcome to the Polycom Community.
The community's VoIP FAQ contains this post here:
Oct 7, 2011 Question: Can I register or is my Polycom Phone compatible with a “XYZ” SIP Server?
Resolution: Please check => here <=
The above leads to an overview of interoperability partners. It does list the UNIVERGE SV8100/ SV8300/ SV8500, Sphericall & ASPIRE-X.
Is the line setup on the Phone end as a shared line?
In addition it is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.
This also allows yourself and others to check against current software release notes.
Therefore the Polycom VoIP FAQ contains this post here:
