Life has its twists and turns. Works in a similar fashion to MGCP. ATA etc. Typically Packet count.

Cisco proprietary protocol used to control Cisco endpoints IP Phones. Packet delay. Packet loss and Jitter statistics is transmitted. This is considered very processor intensive so is only used on low bandwidth links T1 or lower Problems with Digital Voice Bandwidth — 21kbps to kbps per call depending on codec.

A maximum one-way jitter delay of 30ms is advisable. Serialization delay — The time it takes to place the bits on the wire Fixed. QoS can help prioritise voice during bandwidth use peaks. Cisco devices implement a variable sized de-jitter buffer to tune to the connection quality. As a downside it introduces additional delay. Causes of Delay Transmission delay — The physical time it takes for the packet to travel the wire Fixed.

QoS Data applications classes Mission critical — Critical to the running of the business. Codec delay — The time the codec takes to convert voice into a PCM stream. QoS can influence this by putting packets in to a high priority queue.

Queuing delay — The time the packet remains in a queue waiting for transmission. Transactional — Applications interact with the users and required rapid response times. Jitter — Change of delay between packets. Delay — A maximum one-way delay of ms. Packet Loss — As packets are lost there will be holes in the speech. Matches onhttp: Trust Boundary All devices are capable if marking packets for priority. P2P apps etc.

AutoQoS Switch config-if auto qos voip config-if auto qos voip cisco-phone config-if auto qos voip cisco-softphone config-if auto qos voip trust The first three options will only enable the trust boundary if a Cisco phone is detected using CDP. The last command will trust any marking regardless. When configuring AutoQoS it is possible to control whether the downstream devices marking are to be trusted.

By default traffic is sent on a FIFO basis. Scavenger — Non productive and no business need. Queuing Allows changing the default queuing method on Cisco devices routers and switches.

The most efficient way is to mark the traffic at the closest point to the end device. Upstream devices can either trust these markings or generate new marking by inspecting the traffic. Set the QoS on an interface http: Digital based telephony in some cases introduces a small amount of noise on the call.

This avoids the scenario where the listener may believe that the transmission has been lost. Human based rating which scores the quality of speech between 1 poor to 5 excellent.

Machine based scoring from 6. Eight-bit code words allow for a bit rate of 64 kilobits per second kbps. Phone contacts TFTP server and gets configuration file. FXS Analogue Gateway: Phone Boot Process 1. Up to two units can be added. Phone registers with the CME Server listed in the config file.

Phone boots software image. Switch detects PoE capabilities and sends power if required. Avoids cost of replacing switches for PoE switch.

The phone then sends it actual power requirements to the switch using CDP. For non Cisco phones the switch will send the full IEEE The switch then sends a maximum of 6. This standard is able to send power over Gigabit Ethernet. Power Injector — Simple power injector.

Will aggressively try to raise a trunk. Typically a router will have an access list to stop data and voice traffic crossing the Vlans. Will not raise trunk but will if the other end does.

Ideal for receptionist As monitor button but watches the whole phone assigned to the dn Allows multiple phones at the same time to ring on incoming call Allows multiple phones at the same time to ring on incoming call Single telephone number multiple ephones Some scenarios require a single extension number to be assigned to more than one telephone.

Incoming calls are randomly distributed among ephones only a single phone will ring. The DNs are then overlayed to the telephone buttons. Overlay Line buttons Allows an incoming call to ring multiple phones simultaneously i.

A second call will ring the inactive phone but the active user will receive a call waiting beep. Allows the original caller and the recipient of the forward to handle the transferred call directly rather than via the intermediate party handling the media stream call hair-pinning. This is the default. The user then consults the transfer recipient informing them of the call. Only ephones configured with the same reservation group can pick up the parked call.
