Questions on Panasonic KX-TGP500

Q: Hi,
Being Kx-TGP500 a DECT GAP unit it should accept registration of any kind of DECT (GAP) headset. I wasn't able to find any docs from Panasonic stating exactly what kind of features could not work using any other headset instead of KX-TPA50 which is recommended with this.
Thanks, M.
A: No, the handsets are very specific to the bases. If you are able to register a different handset other than what is supported, we cannot say which features will or will not work.
Q: Can the Panasonic kx-tgp500 be used as a wireless IP-PBX without pairing it to a VoIP controller like Asterisk or 3CX. Also can a PSTN VoIP gateway be connected to enable external inbound & outbound calls. If not how does external inbound & outbound calls are been made.
A: No it can not be used as a wireless IP PBX. It is just a SIP phone You will need some form of phone service connected to the phone
