[Bristuff-users] "Cause 34" sum up

[Gunnar Schaller]

Hello Steve,
In Switzland it is not possible to switch from p2mp to ptp without
loosing the phone numbers. Yes I know p2p works as described and that
it would solve the problem, but not for me without loosing my
well-known phone numbers.
I want to find the bug. Can anyone please read my logs or tell me how
to isolate the bug?

Thanks,
Gunnar Schaller
