Spam FAQ

Yes. MultiLine has an embedded real-time spam filter. The service intercepts calls that are likely spam and routes them to MultiLine voicemail.

• Every phone call to a USA MultiLine number is scored in real-time against a spam-scoring AI filter. Any call that is flagged as a potential spammer is intercepted and sent to voicemail without ringing the user's phone. 
• Together with our network partner in the USA, Movius has implemented the STIR/SHAKEN protocol. It provides an additional layer of protection.
  • STIR/SHAKEN is an industry-standard that dramatically reduces the number of spoofed calls. 
  • When the network flags a potentially spoofed call MultiLine will intercept it and route it to voicemail so it does not ring on the user's phone.
  • To prevent calls from numbers that are potentially spoofed from leaving a voicemail, these calls are screened and must press "7" to leave a voicemail. This ensures that in the case of a false positive, real callers will be able to leave voicemails, but robocallers will fail the challenge and be unable to leave a voicemail.
• Our network partner in the USA has also implemented an AI-based text spam filter.
• Movius can work with our customers to define customer-specific controls. 

Spam is an unfortunate reality of mobile communications, but there are several strategies we use for MultiLine that work to reduce the amount of spam received, and features for our users to help combat spam calls that still make it through these measures.

When people retire their numbers, carriers take these numbers for a period of time and shut them off. This causes the systems spammers and robo-callers use to identify the numbers as inactive and remove the numbers from their systems.

End-users can take the following actions to reduce unwanted calls to their MultiLine.

Block calls and texts

MultiLine users should use the number blocking feature that is built into the application so that any spam or robo-caller won’t ring on the phone a second time. Blocking numbers is also the best solution to prevent people or companies trying to reach the previous owner of the phone number from disturbing users. MultiLine applications can support blocking over 1000 numbers, so block away!

Add known callers

Avoid picking up spam calls by adding known callers and phone numbers to your contact list. 

• Any inbound calls from callers in the contact list will have their name display in the inbound call popup. 
• MultiLine Users have three options for adding contacts:
  1. Sync with the existing contact list on their phone.
  2. Sync with an exchange server, for example, their corporate BlackBerry or Outlook contacts.
  3. Add them manually within the application.

Number replacement

When people retire their numbers, carriers take these numbers for a period of time and shut them off. This causes the systems spammers and robo-callers use to identify the numbers as inactive and remove the numbers from their systems. Despite these measures, we have found that about 5% of the numbers we purchase will receive a higher than normal percentage of spam calls. 

If your number consistently gets more than about 5 unsolicited calls per day, and you've tried the above measures to no avail, you can request a new phone number. Go to the support feature in the MultiLine App by tapping Settings, then Help, then Contact Support and your MultiLine Administrator can escalate the situation through the proper channels.
