Hello,
I am new to submitting patches, so sorry if I am doing it wrong. My idea was
to change line 147 in drivers/isdn/pcbit/callbacks.c from
if (cbdata->data.setup.CallingPN == NULL) {

to

if (cbdata->data.setup.CallingPN == NULL ||
sizeof(cbdata->data.setup.CallingPN)>sizeof(ictl.parm.setup.phone) {
