How to setup Hosted SMS – Whistle (Legacy)

SMS Enable Your Landline Number to Whistle.

Only landline numbers are eligible (no VoIP, mobile, etc.).
If we SMS enable your landline number, any changes made to your provider will cause Whistle to lose access to that number.
The number cannot be SMS enabled unless your call-tree is fully disabled.

Contact Whistle Support, support@trywhistle.com for assistance.
A 6-digit PIN will be provided to you.
An automated call will be placed to the landline number within 10 seconds after the PIN is issued to you.
You will need to answer the call, and follow the instructions to enter the PIN.
Whistle will verify the completion.
An LOA (Letter of Authorization) will be emailed to you for signature.
Your landline number will become your Whistle SMS number within 24-48 hours.
