The PBX Information page provides read only information about the extension codecs, other existing extensions and available PSTN lines on the QX200 depending on the active interface.
The PBX Information displays a list of available codecs for the corresponding extension, the list of other extensions on the QX200, their Display names, the SIP registration username and line number (if attached). It also displays the ISDN or E1/T1 trunks state and the destination to route incoming calls. For ISDN or E1/T1 trunks, allowed call types are displayed here. Any shared FXO and ISDN lines are also visible here.
