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.
