Soundpoint 450 IP POE

Dear all,

i am new to the setup of polycom telehones. I am having 17 polycom soundpoint IP450 PoE sets at site. They are all connected to a Elastix Server.

I already configured the phone and they are working fine.

But i am facing one problem,


When i am connecting my phone to PoE and the distance is less than 10meter from PoE port and telephone, it works fine.

But when i am connecting my phone from PoE with a distance more than 10 meter than my phone is getting power but  when i am trying to call to another phone, there is no ring tone after dialing.


Also i am not able to ping the phone if the distance is more than 10 meters from PoE port.

if i am right, Usually it should work until 100 meters .


I checked the ethernet cable (CAT-6) and its ok. The phone are connected at 100 Mbps.


Kindly help me if there is any configuration mistake.

Hello Tariq,


welcome to the Polycom Community.


I just plugged a 10m Patch Cable in my Linksys SRW208P PoE Switch and a SPIP450 just works fine.


Usually the 100m limitation applies to Ethernet in general, not PoE.


I would suggest you check if your switch is able to produce enough Power for all the Phones connected.

Please contact your Polycom Reseller for further support.
