I want you to teach the communication of the SIP server and the SoundPoint450.
(Is there an interface document of SIP server and SoundPoint450?)
There is FW(FireWall) between the SIP server and the SoundPoint450.
Drop is generated at regular intervals in FW.
We should evade this drop.

Welcome to the Polycom Support Community.
Polycom Phones follow the SIP Standard
The Admin Guide for your relevant Software Version can be found => here <=
Using a Switch or a mirrored Port you can easily use Wireshark to gather a Trace and decode the Voice Traffic that way.
An simple Overview of Ports used by Polycom Devices is:
Please be aware that above is only a Guideline and you can change certain Ports in order to suit local Network requirements and depending on the SIP Server other Ports may be negotiated on call setup.

I acquired the log with wireshark.
(refer to the attachment file)
Drop is generated in customer's FW(FireWall) environment at 30 seconds.
I found the communication of every 30 seconds from the log of WireShark.

I want to learn in what setting this communication is revokable.
we cannot provide technical support on your Customers firewall and you would need to work with your Customers IT department on this issue.
The FW(FireWall) trader says that this communication is a setting
I changed the settings keepaive.but, It was ineffectual.
Drop has been generated by the communication of 30 seconds.
I want to communicate for 30 seconds every 145 seconds.
this is beyond the Intention of this Forum.
The Wireshark Trace contains a X-Lite Softphone and not a Polycom Device.
Please work with your Customers IT Team and your Polycom Reseller to resolve this issue.
