add this:
  noccp

>From the pppd man page:

noccp  Disable CCP (Compression Control Protocol) negotia­
              tion.  This option should only be required  if  the
              peer  is  buggy  and gets confused by requests from
              pppd for CCP negotiation.

Reading your excellent log, its clear to me that at least your partners have
a protocol bug in their ppp implementation. Doing noccp, which hopefully doesnt
try to start ccp from your side, might circumvent this.

If this doesnt help, contact them.

And again, this should be discussed on "tech-net", not on "port-amiga". I
copy my answer there, and have set reply-to accordingly.

Explanation below:

> Nov 17 00:50:10  pppd[297]: sent [CCP ConfReq id=0x1 <deflate 15> <bsd v1 15>]
... we request to do either deflate or BSD compression.

> Nov 17 00:50:10  pppd[297]: rcvd [CCP ConfRej id=0x1 <deflate 15>]
... deflate gets rejected by the peer...

> Nov 17 00:50:10  pppd[297]: sent [CCP ConfReq id=0x2 <bsd v1 15>]
... we reuqest bsd compression, and at the same time (the link being
... full-duplex)...

> Nov 17 00:50:10  pppd[297]: rcvd [CCP ConfReq id=0x1 < 11 05 00 01 04>]
... they request hex 11 compression.
> Nov 17 00:50:10  pppd[297]: sent [CCP ConfRej id=0x1 < 11 05 00 01 04>]
... not knowing about it, we reject it.
> Nov 17 00:50:10  pppd[297]: rcvd [CCP ConfRej id=0x2 <bsd v1 15>]
... thats their reject of our BSD request.
> Nov 17 00:50:10  pppd[297]: sent [CCP ConfReq id=0x3]
... we request no compression (well, compression with no protocol)
> Nov 17 00:50:13  pppd[297]: rcvd [CCP ConfReq id=0x2 < 11 05 00 01 04>]
... and, dammit, they request the same protocol we rejected earlier! thats
... their bug, in my opinion.
