•To clear a call the FXO goes
The key thing to note is: FXS devices can receive dialled number information but cannot provide it and FXO devices can generate dialled number information but cannot receive it.
Analog applications:
9.a Vega FXS for analog telephones
Analog telephones can be connected directly into the Vega FXS ports. This allows existing or new (and often cheap) analog telephones to be connected into a VoIP system. This can be especially useful where Cat 5 cabling already runs analog phones to peoples’ desks; the Vega can replace the PBX in the telecoms cabinet, the Cat 5 telephone extensions terminate on the Vega FXS rather than on the old PBX.
A major benefit to users is that they see no change to their working environment and equipment. Also in industrial environments, ruggedised analog phones or cheap disposable phones are much more appropriate user devices than the more expensive,
Vega 50 FXS (SIP) can initiate call transfer (blind and consultative), put a call on hold, and can toggle between a caller on hold and a second called party through use of hookflash and DTMF keys on the attached telephones.
Considerations
•Message waiting indicator lamp operation is not supported – message waiting indication using stuttered dial tone can be used.
•Caller ID is only supplied in sdmf or mdmf formats on the Vega 50 FXS (our range of home gateways support more formats).
