The call forwarding method you selected when purchasing the number will be set by default, and you can also set it as the standard for your other numbers by ticking the relevant box at the time of purchase. You can set two forwarding methods in your settings – concurrent or sequential – with a choice of timeout for the sequential method.

Please note that mobile numbers support only one communication channel. Landline and toll-free numbers include two channels for simultaneous incoming calls by default. Additional channels can be added for an extra fee or upon submitting the required documentation.
