Why Make Calls Using The Mobile Landline Number?
Following a survey of 2000 UK consumers, assessing how they would respond to calls from certain number types, the following information was found:
- 71% were unlikely or would not answer a call from a withheld or unfamiliar number.
- 75% said they would or were more likely to answer a call from a local geographic number.
By overwriting or "Masking" your mobile or home number with your "Business" Number as your caller ID, you are more likely to get answered, it is a more trusted number and hopefully familiar to those new or prospective clients that you are returning missed calls and messages from.
When calling someone's mobile, it is likely they will save your "Calling From" number to their contacts. If you are setting up a Smart Number for your incoming calls, taking advantage of our incoming call management products, presenting your Mobile Landline will keep calls coming in to your main/managed business numbers rather than on a private mobile, which could be turned off, out of signal or just not a convenient time to talk.
