Our standard free trial accounts provide capacity to process two (2) simultaneous fax calls. It does not matter if the call is inbound, outbound, or both – you can send and receive faxes over a handSIP T.38 Fax Trunk during the trial period. If you require more than two call paths (simultaneous calls)’ during your trial, please contact your Imecom representative or email our support team and let us know how many call paths you need.
