SIP Trunks
The X-50 comes equipped to support eight SIP IP Trunks and fifty Direct Inward Dial (DID) numbers. SIP
Trunks are not physically connected, they authenticate over the Internet. Thus, the voice quality of these line are
directly related to the ISP speed. There are several SIP IP Trunk providers on the market and the integration
should be standardized. However, this may not always be the case, and although we do our best to integrate all
SIP Trunks, there is no guarantee, written or implied, that every SIP IP Trunk provider will work with the X-50.
