  • For Onsite CRM users, we recommend an Internet connection that supports a minimum 100kbps per user (both upload and download).
  • For Onsite CRM users with Dialer enabled, we recommend an Internet connection that supports a minimum 200kbps per user (both upload and download) when utilizing a web phone or a VoIP desk phone. Note that this requirement does not apply when using a traditional landline or a cell phone.
  • If the Onsite CRM dialer is being used with a traditional landline, 1 available inbound line per active user is required. The dialer will place one inbound call per agent in order to initiate an outbound dial to the lead.
  • Standard USB headsets should work with the dialer webphone. We recommend using an echo-suppression-enabled headset for best results.
  • Our Quality Assurance team constantly tests our products to ensure that all features are supported by the minimum technical requirements detailed above. Other system configurations may work, but are not formally supported or tested by Onsite CRM.
