Hi, I got a C2821 with PVDM2-12DM modem on on VIC2 - BRI-NT/TE Voice daughter card (2 port).
The problem is, that after I can connect without problems at 33.xxkBit/sec (V.90?), ping from the dial-in device to the C2821 are getting request time out after 3-4 succesful replies, even though carrier/connection remains up. Pls. find sho tech attached! thank you for replying
