I'm set up to call 3 digit extensions at the office ( running 1.4.13)
from home ( 1.6.0 beta7) over iax. 1 out of 3 times the call breaks up,
but only in the home -> office direction. office -> home always sounds
good.
If it were a poor internet connection, I'd expect both sides of the
conversation to be poor. Not surprisingly, each side can ping the other
in the same time - 25-30ms. Both servers have the iax jitterbuffer on.
I could always use a lower bit-rate codec ( now using mu-law ), but I
don't see how it could be a "one way" bit-rate issue.
Any suggestions appreciated.

Sean,
Broadband connections are almost always asynchronous, which means your
download speed is considerably higher than upload speed. With some or our
remote workers they were getting 1.5 Mbps download but only 125 Kbps upload
speed! We ended up having to upgrade their connection to a "business
class" connection, but upload speed was still only ? of the download speed.
You can check your speed both directions with a speed test from a site such as:
