CREATE FUNCTION [dbo].[svf_CutterPhone] 
(
    @source NVARCHAR(4000)
) RETURNS NVARCHAR(4000)
AS
BEGIN
    DECLARE @L INT = LEN(RTRIM(@source))
    DECLARE @phone NVARCHAR(4000) = N''
    WHILE @L > 0
    BEGIN
        DECLARE @cutstr CHAR(1) = SUBSTRING(@source,@L,1)
        IF @cutstr LIKE '%[^-0-9]%'         
            BREAK;        
        ELSE        
            SET @phone = @cutstr + @phone    
        SET @L = @L - 1
    END
    RETURN @phone
