Call Loop's Ringless Voicemail works to U.S. and Canadian mobile numbers and select landline phones. In order to be compatible, a landline must include a voice mailbox provided by their phone service provider. Call Loop does not connect to PBX. When sending to these types of phone systems, users may experience a short ring.
Since determining compatibility is difficult, we give you the option to remove landline phone numbers from your campaign. You can do this by selecting to Send to Mobile #s ONLY when sending a message.
