Reply To: ECT – Explicit Call Transfer

wallis dudhnath

Explicit Call Transfer – ECT – is a ISDN supplementary Service. GSM is based on the ISDN (Q.931) ETSI specifications.

The ECT supplementary service enables a user (user A) who has two calls, each of which can be an incoming call or an outgoing call, to connect together the other users in the two calls, into one call.
