is the same cost as

nobody seems to know when a version that works will be available. It
looks to me like this is some sort of timeout issue. Does anybody
have a workaround to allow this to be used? (I know about UniMRCP,

Thanks for the pointer. Valgrind wasn't needed since Asterisk MALLOC_DEBUG
was enough.
It took almost 1.5 hours in GDB, but I found it. Because I was having
problems with res_speech_lumenvox, I was using UniMRCP, which uses S

I looked at the code in question and I don't see how the below is possible.
What am I missing?

Who's responsible for it? Lumenvox is the only place that distributes
it, but they can't do anything with it since they get it from Digium.
However, the current version doesn't work with Asterisk 10.7.1 and the
latest version of Lumenvox software (it appears that a timeout is
being set to zero).
I'm getting cycles of repeated crashes which occur and then stop occurring.
Looking at the dumps via gdb shows that something peculiar is happening
that looks like memory corruption:
Program terminated with signal 6, Aborted.

I'm migrating from Asterisk 1.6.2 to 10.7.0. In 1.6.2, I made a small
patch to allow specifying an address for RTP media. That worked. In
10.7.0, this appears to be built in with "media_address", but it doesn't
work for me.
My Asterisk server has multiple addresses, all global address on two

When I thought that it was echo cancellers fighting each other, that's
exactly what I wanted to do.

No, on the card.

I'm having a wierd clipping issue with one employee who's using a phone
over a satellite Internet. He was sold that system specifically for use
with VoIP. Ping times show average round-trip time as around 700 ms with a
range of 560 to 841, so considerable jitter.
Things work fine when he's talki
