BLF problem on SoundPoint IP 650



I am using Polycom SoundPoint IP 650 with the 650 expansion unit to monitor other extensions.

When an extension is idle the LED is off not showing anything (I was expecting it to be on green).

When an extension receives a call the led will blink, and on a call it will be on steady.

After the call is hang up, and another call come in, the LED will not indicate anything. It will not indicate even if the extension is on a call.

So, basically it displays a status one time, no more. I don't know if there is a time limit that it will reset itself, but it did not change for many hours maybe a whole day.

If I power cycle the phone it will reset this 'counter' and will again enable one call indication per extension until the next power cycle...


Any input is appreciated.

Re: BLF problem on SoundPoint IP 650 (with PortaOne)

Just an update.


The problem was with compatibility with PortaOne PortaSwitch switch.


PortaOne claims they support Polycom phones using the relevant RFCs.


But Polycom simply told us (after we wasted hundreds of hours on this problem) that PortaOne did not run compatibility test with them end of story.


The bottom line is that if you are running PortaSwitch and you need BLF functionality, do not use Polycom phones.


Hope that it helps.

Hello Gulli,


can you follow up this statement with a Polycom ticket reference usually starting with 1- so I can confirm this?
