Account Registration
Registering an account makes it easier for the IP phones to receive an incoming call or dial an outgoing call. Yealink IP
phones support registering multiple accounts on a phone (T19(P) E2 phones only support registering one SIP account;
CP920 phones support one SIP/cloud account or two PSTN accounts); each account requires an extension or phone
number.
