A client has 750 analogue extensions and 150 analogue lines, acouple of PRI and 30 chnl SIP line. He wants an SCME but is not willing to relinquish the analogue xtns because of costs and analogue lines since they are well advertised.
How best do I integrate them extnsions on the SCME? Is it via FXS and FXO gateways or I slave 2 x OS7400 complete units to the SCME?
