[VoIP] Question on connecting old dial telephone

[Jayson Smith]

Hi,

    I think RP under Asterisk would be cool! Especially if two Asterisk
systems could RP to each other, even though that's totally unnecessary. A
question though? I'm wondering, would you have Asterisk pulse as quickly as
possible, or, for old times' sake, implement panel-like timing for each
digit? Thanks.
Jayson
