Подскажите, пожалуйста, что лучше использовать в качестве шлюза E1<->SIP as5400xm или as5400hpx. Планируется использовать 16*Е1 потоков, кодек только g711alaw.

P.S. Судя по sh run обоих: частота процессора больше у XM, но HPX есть L3 кеш, на количество оперативной памяти особого внимания не обращал: думаю, что перекинуть можно будет.
