Disconnection is the problem?

The error message is a good hint. The other end of the PPP link, most
likely the phone you're using, does not support lcp-echo-requests and
-replies (for really no good reason as the serial links aren't that
reliable).

Setting these to zero will effectively disable echo requests and
replies. man pppd will tell more.
