how to prioratize bandwidth for voice and data..

Hi

Can somebody let me know if we can prioratize bandwidth for voice and data in ERS 5520 or contivity 1010..

Thanks a lot..i think i got what i wanted..is there any standard procedure i should follow in QOS settings while configuring voice and data over a MPLS link..

I have a 4 MB MPLS connection connecting 2 BCM 450s in different branch offices..Problem is the data is working perfectly fine..but there is one-way speech path at times in voice..I can ping the IP phones in from both sites at all times..is there some QOS settings i should be doing..The codec used is G711..

there can be many reason for "One way speech" but QoS is not going to help (to get rid of it), it helps with the "quality" only.

One way voice could be related to configuration, VLans, Ports being blocked, Firmware for phones, Patches on the BCMs, Codec mismatch, speed and duplex Lan port settings.

Sometimes it's simple stuff like a Subnet mask typo if you don't use DHCP... some users phones don't go to the default gateway if the subnetmask is wrong and therefore you have "oneway voice"

if you have the problem intermittently, do a sniffer trace to see if you are getting the RTP Voice streams, if you are missing one side, check where it stops and why by moving the sniffer closer to the source (who's ever the voice is missing)....

slow agonizing process but that way you will have a direction to follow.
