Good day All.
We have had our node up at VE3LSR / VE3UOR for a few months and we all have
learned a lot about configuration and operation. It is ACID install and
version id is 300.3.
On our asterisk system, we support three nodes:
27211 VE3UOR UHF repeater
29133 VE3LSR coupled through a RLC-DSP404 controller (often connected to
VE3UPS and VE3UHN), and
29154 VA3LSR remote link for VE3LSR into VE3MUS not too active ad-hoc
RF link.
I have also been testing out iaxrpt and the WebTransceiver clients.
I am on these systems and the results have been promising. I do notice some
clipping on the audio on some stations. Initially I thought it was
amplitude related over-driving the URI-FOB, but I am now beginning to
suspect that it may be network related and in my research I hear the term
jitter being used which if activated, adjust operation on the receiving
end only.
It may be that the system is not powered enough to drive the three uri-fobs.
CPU show about 25% busy.

We do think that the system is sufficiently powered.
We are looking for comments & guidance. Are we expecting too much from the
system having three fobs connected? We do have good bandwidth into and out
of the site.
I am listening to other systems most not to busy, so I am not yet able to
get a good reference point.
I have not dabbled with the codecs much, but have been focused on using
ulaw. I am also testing with GSM lower bandwidth.
So as I said before, thoughts or suggestions are welcome.
