We are attempting to set-up a 3640 router to do both incoming and outgoing calls to Win2K servers. We are using a PRI at the 3640 and a multitech 28,800 modem at the server.
Communication including MS-Chap works fine from the server to the router. However, when the router dials the server the connection fails during LCP in the PPP set-up. The router sends LCP CONFREQ but receives none back from the server. The set-up times out after 20-seconds and the line is disconnected.
Two things we are considering is a speed issue, which we have been unable to resolve and possibly ppp ACCM. When the server calls into the router it uses ACCM during the LCP negotiations. However, the router goes directly to AuthProto MS-CHAP.
Any ideas???
