Users hear themselves?

[PuterBD]

Hi Gang,

I'm having a weird issue!! A few weeks ago we upgraded our customer's IP Offices to 4.2 (14). They have 9 different sites and only one of them has been complaining of this problem since then.

This site in particular has about 10 users. They are all complaining that they can hear themselves while talking on their phones. It doesn't matter if they are internal or external calls. They explain it as that after they say something into the receiver, a split second later they can hear what they just said. Everybody there is using 5610 phones.

I am not sure what other information you might need, but I would be glad to supply whatever I can. Any help is much appreciated.

Turn off "skitsofrenic" in the telephony options.

Then get your routing and QoS sorted out if that fixes it

Are you using voice VLAN's in the network?
If not, let have someone look at the switches/network and create a Data and Voive VLAN and like riddle says turn on QOS then.

This will solve a lot of problems

Yes, they have VLANs setup for voice/data. Turning off Direct Media Path doesn't seem to have helped sadly. They have an office and a construction trailer outside of the office and are now reporting that if someone is on the phone in the office and someone is on the phone in the trailer that the person in the office can hear the person in the trailer talking through the phone.

Any ideas?

AGC was turned on. They turned it off and said it helped somewhat, but the problem still exists. That's a good start though, so thanks. Have any other suggestions possibly?

Do they have the volume all the way up ?
This can cause this too

Ive had this same problem with a site recently using 16xx phones - Avaya have recently added an Echo Return Loss to the VCM tab of the system section.

I tried setting it to all the different levels 0, 3, 6 and 9 and since changing it to 9 almost a month ago now I have had no further complaints.
