we have some 7985.
They work fine in the corporate voip network or when they calls pstn numbers directly.
They work with a lot of troubles (one way voice, noise, etc.) when they call passing a trunk qsig with an ericsson PBX (BP250)
When I see phone statistics during these calls, I find:
- packet loss (from 0 to 10%)
- Audio rate (receive) changing randomly from 0 to 64 Kbps.
7940 and 7961 don't have the same troubles using the trunk
Has someone used 7985 with a qsig trunk?
