[Asterisk-Users] Single FXS port with multiple phones ?

[James Pooton]

Excellent, thanks for the info.  That hiss is interesting; maybe all the
extra wire makes it tougher for the SPA to drive.  In any event it sounds
like it will do what I want. Thanks.. :)

James,

the SPA's have a "FXS Port Power Limit" which is 3 by default. The
range is 1-8. I have a SPA 2000 with 6 phones on one port (entire
house wired to one port) which works OK as long as your phones do not
rely on power from the line (cordless phones, etc. are fine). On the
second port I have just one phone, no problem using both ports
simultaneously.

The only "problem" I have is the hissing noise on the line -- it seems
to be higher than what I'm used to from regular telco lines. I'm
confident it's due to the wiring in the house, not the number of
phones. I had all six plugged in directly, works fine, no hiss; if I
leave just one plugged in and still use the house wiring, more hiss.
It's probably to do with the impedance setting, but neither one seems
to make a noticeable difference.
