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.
