My UC560 worked fine until about a week ago, it hung and lost some of the config in NVRAM.  I copied over a saved config and all was back up and running.  When remote offices call in and try to leave voicemail, they get "beep beep beep".  Outside callers and extensions at the main office are fine.  Cisco TAC suggested upgrading the device using CCA.  I did this upgrade to software pack 8.6.2, erased the voicemail flash.  Still get the beep beep beep.  TAC said the 711ulaw codec may need hardcoded but it already is and worked fine until the crash.

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.
