I have an analog/SIP voice GW(Patton) with FXO port connected to public land line.
On this analog GW, I have also analog sets connected to FXS ports.
This GW is sip-connected to CUCM 12.5.1: on which I have hundreds of SIP phones
1°) For outbound calls thru this analog line, this FXO analog trunk can be used by ALL phones of the installation, either SIP or analog : YES/NO?
2°) For inbound calls thru this analog line, this FXO analog trunk can ring ONLY 1 phone of the whole installation, that I need to map to the default incoming of the analog line (or the whole public number): YES/NO?
Or can it ring any phone of the installation? I guess no because analog dont do DDI like E1/T1...
