[Freeswitch-users] mod_nibblebill and dynamic conference

All: We are currently exploring the possibility of using mod_nibblebill and integrating it with a conference. It seems like it offers all the features and more that we need. The way we create a conference now is as follows: originate sofia/gateway/url/XXXXXXXXXXX &conference(myConf+flags{moderator,wait-mod})

From the mod_nibblebill wiki page it seems like we need to set a few variables for the B leg:

enable_heartbeat_events nibble_rate nibble_account= I was wondering if there is a way to set these variables via the API call shown above where the conference is created. If not, what options do you recommend to accomplish this? Thanks in advance, Alfredo
