ello,

A business installed DECT in your enterprise and since the first day of production I experimented problems, 1 year later I got the same problem

When I open the phone to do a call or when a I receive an new call, a weird noise appearing, I can't barely listen anything. Sometime it can take 4-5 minutes to get back whenever i change locations. Sometime I close the line and 2 sec after it's ok. it's appearing in two different site and all my phone are Aastra 622d. The aastra and mitel support say we weed to upgrade our mitel because we can't go the new version of dect 6.0. I have a doubt it will change something !

We try to deactivate an codec and no ameloration.

Here a topo of my architecture.

OpenMobility Manager
SIP-DECT 5.0SP2.

Mitel 3300
Release level 6.0 SP3
Active software load 12.0.3.15
Platform MXe-III

Any comments ?

Thank you
