QOS a possibility?

I want to implement QOS for VOIP traffic between Branch Office IP phones and Headoffice PABX.

Basic network diagram is as follows

Nortel IP PHONES (Branch Office)

|

L2 ordinary Switch

|

Cisco 1841

|

|

-----MPLS WAN-----

|

|

Cisco 1841

|

Cisco ASA

|

Cisco 3560 (with multiple VLANs)

|

NORTEL PABX (Headoffice)

Muhammad

Re: QOS a possibility?

Hi,

there are several networks succesfully running such a scenario. Make sure your VoIP and signalling traffic is marked properly, negotiate respective SLAs with your ISP and use LLQ. In the MPLS network qos will be based on labels and contained experimental bits. This is however not your concern, as it solely is inside the MPLS network and invisible to the customer.

As a starting point for you, "auto qos voip" will cover all VoIP needs.

If you need a more detailed QoS policy you could start with "auto discovery qos" followed by "auto qos" on the router.

A more detailed explnation can be found in "Enterprise QoS SRND"

Hope this helps! Please rate all posts.
