[Freeswitch-users] clock sync troubles

Hello folks, I would like to know if FreeTMD will allow two different clocks to be used for two different ISDN cards? The BRI running on the NTT (telco) clock and the PRI card running on its own hardware clock then pass an incoming call on the BRI card over FreeTDM to the PRI card. Would this avoid clock sync troubles? Regards -- Javier Aristizábal
