Until today, I thought it might be related to the interaction between the Nokia firmware and Asterisk, but if Rafael says 2.6.9-78/bluez-2.10.3 would be working? https://issues.asterisk.org/view.php?id=15075 now has a patch which at least cures the symptoms. I do also see some kernel errors via dmesg: btusb_isoc_complete: hci0 corrupted SCO packet hci_scodata_packet: hci0 SCO packet for unknown connection handle 0 hci_scodata_packet: hci0 SCO packet for unknown connection handle 0 hci_scodata_packet: hci0 SCO packet for unknown connection handle 0 hci_scodata_packet: hci0 SCO packet for unknown connection handle 0 hci_scodata_packet: hci0 SCO packet for unknown connection handle 0 btusb_isoc_complete: hci0 corrupted SCO packet hci_scodata_packet: hci0 SCO packet for unknown connection handle 46 hci_scodata_packet: hci0 SCO packet for unknown connection handle 0 [...] -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
