DECT Call drops after approx. 2 seconds

Hi,

I successfully managed to compile the DECT kernel, the libs and asterisk. 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.

Does anyone know what the reason for this behaviour is? See the asterisk-log below...

Thanks in advance,
Johannes Graser
