In Our Heads
------------------
- we're suspecting that the presence of the TC400B is making asterisk behave
in different ways that lead to what we're now calling a hang (that is the
apparent change in the system since it started mis-behaving)
- as such we're considering removing the TC400B to see if the system
stabilizes however removing it may remove the possibility of further
diagnosing this issue and trying fixes
- of course, we're trying to manage customer expectations and
satisfaction at the same time


...other possibility:

- instead of removing the TC400B, change the IAX trunk codec to
GSM instead of G.729... this would prevent the TC400B usage and
may lead to different (as in stable) behaviour

More troubleshooting ideas ?

You are right, changing the codec to something other than G729 or G723 will prevent the TC400B from being used and would allow you to isolate the issue.

However, I'm working on a new codec_zap / transcoder / wctc4xxp interface to primarily handle a condition where some remote system sends a G729B comfort noise packet even though we didn't advertise support for it.

I'm soon going to petition for this interface to be merged into the trunk, so if you would like to try the branches out now and need any help, please contact me directly.

Thanks,
Shaun

Of course, future possibilities of changing codecs, removing the TC400B
or others are open (such as: I guess we enabled the 1st voicemail
account as test
on the same day that we installed the TC400B -- could it be the change ?)


Do you have MWI enabled? We are suspecting a similar SIP deadlock on a
system that may be caused by it. Although our version is 1.4.17. There
is some mention of it on: http://bugs.digium.com/view.php?id=10953

We're still open to peer feedback, of course.
Post back later.
