I have an SPA9000 and 5 VOIP Phones no Cisco (current firmware 6.1.5) working fine.
My issue is when I attempt to transfer a call from some phone to another it drops the call, the same problem when i attemp call hold or conference.
It's There any problem with compactibility with Third-Pard Phones?
Any help welcomed!

The spa9000 is designed to work with the spa9xx line of phones. When using other brands of phones, advanced features will likely not work as you have seen.
