### Answer Yes. By default the SMS is sent to the caller's number, but you can choose to send to a different number instead — either a static number or a dynamic variable such as

{{customer_phone}}

[(1) ]() [(2) ]() . This applies to both the Send SMS tool for single/multi-prompt agents [(1) ]() and the SMS Node for conversation flow agents [(2) ]() . Since the caller provides the number mid-call, you'd typically extract that number into a dynamic variable and reference it as the SMS destination [(1) ]() [(2) ]() . Note that this destination configuration only works when using a phone number that has SMS enabled, or an SMS-approved Retell number [(1) ]() [(2) ]() [(3) ]() .
