 Yes, both phones reregister after the call drops.

Attached are the debugging logs, starting immediately before placing a call and ending after the phone reregistered.

I also can register PPs in asterisk, call them and place outbound calls from these PPs, but as soon as the connection is established, it takes about 2 seconds until the call drops, the PP loses connectivity and re-registers at asterisk. Whithin these 2 seconds the connection works in both directions correctly. I use the PCI Com-on-Air Card a Gigaset A58H PP and an older Gigaset 4000 Comfort.
