So how do you connect your SIP Trunks to your Panasonic Telephone System and which systems are compatible?

SIP Trunks can be connected to the KX-TDA50G Phone System, KX-TDE100, KX-TDE200, KX-TDE600 or KX-NCP500 and KX-NCP1000 Phone Systems by using the correct cards.  The KX-TDA50G has the ability to have up to 8 SIP Trunks by adding a KX-TDA5450 and KX-TDA5451 SIP Trunk cards.  Any of the KX-TDE or KX-NCP Phone Systems can connect to SIP Trunks by using a Panasonic Codec (DSP Card) and the correct amount of IP Trunk Licenses.   There are three DSP Cards to choose from depending upon size and potential growth in the future.   KX-NCP1104- 4 Port DSP Card, KX-TDE0110- 16 Port DSP Card, and KX-TDE0111 64 Channel DSP Card.   Each card comes with a specific amount of IP Trunks and the 16 and 64 Channel can be upgraded by adding more IP Trunk Keycodes.  The NCP500 can have up to 8 SIP Trunks, while the NCP1000 can have up to 32 SIP Trunks. Any of the TDE Phone Systems can have up to 64 SIP Trunks on the latest release software.
