You possibly trans-code some calls like G711 to/from gsm/ilbc/g729/g723 etc... Try to change architecture - some redundant setup and more servers, split TDM hardware to more boxes, and it will work... As simple as that. If you don't believe, cut down traffic to 4 E1, by not configuring second card in dahdi/system, then add one E1, wait day or two etc... you will measure how much your box could handle. In my experience: recently bought servers go with max 7-8 TDM connections and not a single one more. Simply - when 'soft modems' were popular on market - noone tried to put 4 soft-modems in one box. It was designed to use main CPU for many functions. Now - you try just to put many 'soft' cards into one box - without any check up if this architecture it could handle that. Even 'smart' ss7 cards from dialogic or synway or any other vendors have some limits with max cards per box... Maybe - 1st step should be optimize your dialplan? -------------- next part -------------- An HTML attachment was scrubbed...
