[Asterisk-Users] Questions from a working doctors' office installation

Michael,

Huh... interesting... I had (and actually still do) have 1.2.5 version
perfectly; it's been >60 days since the last restart so I figure I
would have noticed memory leaks until now. This system is in a small
real estate office with 15 extensions but with hundreds of calls a
day, plenty of transfers. However, it's SIP only, no hardware, no IAX.
Perhaps the memory leaks are specific to certain hardware or protocol
or activity. Anyway, I'm not going to argue there are no memory leaks
-- if you have them, try an upgrade :).

Yes. Here's what I do. I symlink the executable asterisk ->
asterisk-1.2.5 and directory modules -> modules-1.2.5. When I want to
switch versions, I change the symlinks for those two keeping
everything else the same. No problems going back and forth, at least
not between 1.2.x versions. When you build asterisk, don't do a "make
install" but simply copy the executable to asterisk-VERSION and all
.so files from the build directory to modules-VERSION -- i.e. cp -a
`find -name '*.so'` /usr/lib/asterisk/modules-VERSION/. I run this in
a chrooted environment, but you don't have to.

That's something to the -biz list, probably but you may contact me off
list if you need suggestions.
