Whoo Hoo! I managed to get * up and running last night.
My most pressing problem is that there is a considerable amount of
hiss heard by the called party when using a SIP phone (xten or
GXP-2000). I’ve tried two different computers with two different
headsets, and the hiss still remains when you should be hearing
silence (or near silence).
The hiss does not occur when you’re on one of the extensions of the
legacy PBX (Nortel).
Anyone have some ideas on where I should be looking?
Basics below:
PSTN (via PRI) à * à PRI à Nortel Meridian
I’ve got a basic dial plan setup to forward most calls through * to
the legacy PBX.
Thanks!

I test headsets by doing record/playback with audacity sound editor on a
linux workstation. So far all of them have high frequency hiss and
noise. I record and then apply a low pass filter and the playback sounds
fine. When I have the time I will be testing some usb headsets.
I get the hiss and noise with softphones using all headsets I have tried
so far. I don't get it with grandstream budgetone 101 phones or phones
connected to ata's.
