Table 5-23. Local Number for Dialback
Parameters Description
Dialback Phone Number Select this parameter to enter the phone number which is used by the ISP to
dial back FCD-IPM. When FCD-IPM wants to dial-up to the ISP, the ISP uses
this number to identify and dial back FCD-IPM (similar to reverse charging). In
this way, the PTT bills the ISP and not the caller. This feature is only useful
when dialback is enabled on both sides.
Dialback Sub-Number Select this parameter to enter the extension used by the ISP for dialback
purposes.
