[Freeswitch-users] are there any high performance rtmp dispatcher solution, comparing to the opensips/Kamailo (for SIP)?

hi guys, i have an opensips as SIP dispatcher and loadbalance of several freeswitch (behind). For now, if the end-users use flash rtmp web phone to make a call, the opensip cannot handle the rtmp request, although the freeswitch has mod_rtmp. in this situation, could i use a freeswitch at the front of opensip, and woks only as rtmp proxy as below? FS (rtmp dispatcher) --> opensips --> FSs if not, should i use the 3rd party rtmp gateway/dispatcher to replace the opensips? are there any high performance rtmp dispatcher solution, comparing to the opensips/Kamailo (for SIP)? i am new to this area, thanks for any suggestions. -iamsyt
