voipGATE supports the usage of several DIDs or DID-prefix on one single user account. That way only 1 single SIP registration is required, the dialled DID will be transported in the INVITE's To: -Header. This setup allows to use several DIDs (e.g. 1112,1117,1119) or a block (1110-1119) or DID prefix (e.g. 111* which would include 1110-1119 and 11100- 11199 and 111000-111999 and so on) How will I have to setup this in 3CX? I saw that I can configure several accounts per voip Provider and assign 1 DID per account on 3CX. However in this case there would be several DIDs on 1 single account.
