Absolutely bugger all: [call setup stuff, indicating that isp0 is in fact in debug mode] [at this point I phoned frog] Jul 31 21:00:11 frog isdnd[338]: CHD 00624 I4BTEL answering: incoming call from NotAvailable to MyNumber () Jul 31 21:00:11 frog isdnd[338]: CHD 00624 I4BTEL incoming call active (ctl 0, ch 1, tel0) Jul 31 21:00:22 frog isdnd[338]: CHD 00624 I4BTEL incoming call disconnected (remote) Jul 31 21:00:22 frog isdnd[338]: CHD 00624 I4BTEL cause 16: Normal call clearing (Q.850) Jul 31 21:00:22 frog isdnd[338]: CHD 00624 I4BTEL connected 11 seconds [at this point I could no longer ping anything on the remote end of the link, yet spppcontrol isp0 reported that the connection was in the network phase.
