How to configure Asterisk for LIPZ4 1.3.11
The cheap (?) ZIP 2 phone ($100) comes without any display, but all other typical features like speakerphone (not full duplex!), voicemail indicator, hold, conference, transfer. STUN and UPnP support for operating the phone behind NAT is apparently provided as well (documentation error on the Zultys web site?). Paging support is available it seems (= announcement through the speaker).
Next to a display, instant messaging and a 4-port switch the ZIP 4×4 ($350) includes encryption, a feature rarely found in IP phones. However STUN, UPnP and voice compression are missing (g.711 codec only). From their web site:
- Does the ZIP 4×4 support voice encryption?
- Yes. The ZIP 4×4 can use Secure RTP and AES encryption to transport voice traffic in a secure manner. Users can engage this function before or during a call by pressing the Encrypt button on the phone.”
