Can anybody tell what are exact differencies in parametar setting beetween modem and fax pass-through modes (like values of static jitter buffer and so on...). In every documentation I find only value for static jitter buffer for modem (200 ms).
If both are configured globaly (as system parameter) on Cisco voice-gateways (for example - 28xx, 38xx or AS 5xxx) in which cases these two modes can cause malufunction of one of them and why?
When the gateways detect a data modem, both the originating gateway and the terminating gateway switch from dynamic and adaptive buffers to static de-jitter buffers.
The use of a static de-jitter buffer is required for modem passthrough because the adaptation process in a dynamic de-jitter buffer causes a retrain on the modem connection. When the modem call is concluded, the voice ports revert to dynamic jitter buffers.
Modem and fax passthrough are treated the same internally...as fax passthrough is just a special case of modem passthrough.

loadbalancing is one of the more complex items in hardware forwarding. of course we have talked about it many years on cisco live (id 2904) with ever incrementing more detail. and there is the support forum article on loadbalancing.
