Understanding the Routing Sequence
1. Ring
No changes need to be made to this section. Please ensure this is left on and the timeout is set to 30 seconds.
2. Forwarding
Toggle: Leave ON
Forwarding Options: Choose where the call should go:
Extension: Forwards to another colleague's ONSIM line (has to be on your account).
Groups: Not available with this product
External: Forwards to a non-ONSIM number (like a home landline or a different mobile).
Forwarding Number: Type in the external number manually in correct 44 format. Please see below for details on the number you can divert to.
Timeout: How many seconds the call should ring for.
Our virtual landline service supports seamless call forwarding to standard UK landlines and mobiles.
Allowed Numbers
You can divert your calls to most standard UK numbers. These include:
UK Landlines: Numbers starting with 01 or 02 (e.g., 0161, 020).
UK Mobiles: Standard mobile numbers starting with 07 (e.g., 07700).
UK Non-Geographic (Standard Rate): Numbers starting with 03, which are charged at the same rate as landlines.

International Numbers: You cannot divert calls to any number outside of the UK (any number starting with 00 or + followed by a non-UK country code).
Premium Rate Services: Numbers starting with 09 (often used for competitions, chat lines, or specialist advice).
