[Freeswitch-users] Ringing instead of MOH for valet parking

Hi all, Is there a built-in way to have callers hear ringback instead of MOH when they are valet-parked? I do not mean to replace the MOH string with a ringtone, which would ultimately cause the caller to hear ringing whenever put on hold…. I am looking for an actual option. It is probably trivial to change in the code, but I thought I would ask anyway before I start messing around… Thanks, All the best, Emrah
