Configuring DA Discovery for Dial-up Networks

If the UAs or SAs are separated from the DA by a dial-up network, you can configure DA discovery to reduce or eliminate the number of discovery requests and DA advertisements. Dial-up networks usually incur a charge when activated. Minimizing extraneous calls can reduce the cost of using the dial-up network.

Note –

You can disable DA discovery completely with the method that is described in Limiting UAs and SAs to Statically Configured DAs.
