I have the folowing situation:
I have configure a 2821 mgcp gateway on CM 5.1.2 with EVM-8FXS/DID. On the fxs I only have configure a CSS and the prefix field. Afther i pick up the fxs phone the CM dials the prefix number and the is made sucessufly. If for same reason the called number disconect the call and the calling phone stays off-hook the fxs phone keeps calling the prefix dn every 3 seconds. Is there any way for the callmanager not do dial the prefix dn from the hot line if the hot-line stays off-hook.
