Does anyone know if it is possible (and then how) to specify the RTP port range on cisco TDM gateways (3640, 5300, 5400, 5800, etc) It seems inconceivable that it can't be done on cisco hardware, but i havn't been able to find any information on how to do it, i've talked to several cisco engineers that don't know how to do it either. Again, sorry for the OT question tavis
