Polycom SoundPoint Pro SE-225 Problem

SOURCE: Polycom Soundpoint IP 501 - URL call is disabled

I get this same problem. The phone icon turn white and "url call is disabled" I can place calls and receive incoming calls, but cant place outgoing calls, unless the phone is rebooted

As you have probably found, SIP phones are not supported until R5, which just came out.

SOURCE: what is the default password for Polycom

Default Passwords:
To get into the web interface, the default username/password is "Polycom"/"456" (Note that this does not work with Safari 1.2.2.)
To get into the Admin interface on the hard phone, the password is "456". (Prior to v1.3.1, the web interfaces to the phone uses "Polycom"/"SpIp" as the username/password.)
The "user password" (not used much) defaults to "123".

To reset a lost admin password to default: at phone boot, during the 5 second countdown, push/hold 468* on the phone. Enter the phone's MAC address as the password. This will reset network info but keep peers loaded. Tested on Soundpoint IP 650.

Testimonial: "Thanx a lot. Although I had managed to find the password for console but the web interface password was still missing. :-)"

SOURCE: i am unable to push the configuration files into polycom soundpoint ip 330 through tftpd

This means the phone's SIP application has been erased. You will need to download the SIP app and BootROM from the Polycom support page, host the files on a boot server, and then point the phone to this server from the server menu so the phone will reboot and download the files.
