Hi everyone,

I have a strange problem with header-compression on my AS5300, IOS
12.1(5)T. Basicly, it works fine for analog 56K dialup: both ways,
sending and receiving (I tested it on Linux). For analog, I have header
compression on GroupAsync interface.

However, when I connect using ISDN (external TA - Intranet NetMod),
VJ Compression is sucessfully negotiated, but only Linux sends packets
in compressed form. AS5300 sends them uncompressed (header compression
is set on Dialer interface). According to statistics on AS5300,
VJ compression is turned on, and compressed packets are received, but
none are sent. I tried setting compression-connections to a high amount
- it didn't help.

Is this a known IOS caveat, or some other issue?
