Need help in Cisco SPS504G configuration; after I submitted changes, the phone shows "Checking DNS". I am not sure about the 'Display Name:', 'User ID:', 'Password:' and 'AuthID:' entries under 'Subscriber Information'.

Hi PC Chen,

We don't officially support Cisco phones, however as long as the phone supports SIP - it should work fine. The registration process will be similiar to the Grandstream phone: https://www.ringroost.com/device-config/ip-phones/gxp2160

Cisco SPS504G

Reset to factory default then

Under "General" be sure to set "Line Enabled" to true.

In the "Proxy Registration" section set proxy to "ringroost.com". Also, ensure that use DNS registration is set to "Yes".

In the Subscriber information section:

Display Name: SIP Username (found on your "SIP Phone Control" on your RingRoost PBX)

User ID: SIP User (found on your "SIP Phone Control" on your RingRoost PBX)

Auth ID: SIP User (found on your "SIP Phone Control" on your RingRoost PBX)

Password: SIP Pass (found on your "SIP Phone Control" on your RingRoost PBX)



- Let us know if you are still unable to register and we will setup time for remote desktop support.

Thanks,

RingRoost Support Team
