I see in the example in the SER documentation for forward-on-no-answer to voicemail that they use something they call a sink port. Anyone know what this is? I'd like to do the following, as goes pseudocode: ... db-voicemail flag set? set timeouts to 16s, initiate call if doesn't go through to registered destination, send to vm else flag not set? set timeouts to 180s, initiate call if doesn't go through, issue 487 end Is the sink port something I can or have to set up? Do I need it for this? It seems non-obvious. Thanks. -Keith, TSS
