Polycom Time and Date
The date and time one the phone can be set by synchronizing it with an NTP server (Network Time Protocol server). This can be done by logging into your Polycom phone through a web browser. Log into the IP address of the phone:
http://192.168.0.102 for example.
- Choose the "General" tab
- Default username: "Polycom"
- Default password: "456"
- Choose "Time"
- SNTP Server: pool.ntp.org
- GMT Offset: -5 for EST
- -6 for CST
- -7 for MST
- -8 for PST
- SNTP Resync Period: 86400
Choose "Submit" to submit your settings and reboot the phone.
There is one potential issue with Polycom phones and the time settings: The DHCP server will ALWAYS over-ride the time settings from the WWW interface. Therefore, if the time is not correctly set on your DHCP server (the server/router - where the Polycom phone obtains it's internal IP address) then the time will be incorrect on the phone itself.
If the above settings do not correct reset the time settings for the phone, then the phone is obtaining it's time settings from the DHCP server. You must then, check the DHCP server for the correct time.

setting Polycom 501 time
Just got a new Linksys router (rv042) and now our time is incorrect on all our phones. The time is correct on the router and the phones are still set up correctly and have been rebooted multiple times. I set the router to use the NTP server of pool.ntp.org with a EST time zone.
The router is showing the correct time but the phones are still incorrect at 5 hours ahead as if the offset is not being used.
This all began when we replaced the router.
Anyone have any ideas?
Thanks
Linksys RV042 - no SNTP
The Linksys RV042 does not provide SNTP (Simple Network Timing Protocol). The Polycom phones will therefore not obtain the correct time from them and will default to Greenwich Mean (EST+5).
There are two options:
1.) Purchase a different router - d-links usually work well.
2.) Obtain configuration files from your hardware provider and edit sip.cfg to tell the phone to use the internal NTP settings you provide in the WWW interface. That is beyond the scope of this document and per Polycom reseller agreement, can only be provided by your hardware provider.
Linksys RV042 and Polycom phones
The DHCP server on the Linksys RV042 is broken in that it gives out a GMT offset (option 2) of "0.0.0.0"
This overrides the Polycom phone and configuration file settings unless the "tcpIpApp.sntp.gmtOffset.overrideDHCP="1" is set to one. Older Polycom firmware(<2.0) does not accept this setting. The only solution for older firmware phones is to set a static IP address on the phone.
Any way to override this on the phone itself?
