The Fax Negotiation parameter allows up to three FAX algorithms to be selected, separated by a comma. The sequence represents the priority. When this parameter is configured, it takes precedence over the Fax Digitizing Rate configured in CLI Procedure for Setting the Voice Profiles (4460). The actual speed and FAX algorithm used is done through end-to-end negotiation internally and is hidden from the user.
To set the desired fax algorithm negotiation settings, enter:
CLI> set voice switchingProfile faxAlgNegotiate
