Is there a previous version that this works in with the same setup?
By: Guilherme Farinacio de Carvalho (gfarinacio) 2010-01-22 04:12:48.000-0600

I don't know. When have time I will going to test in previous version but what version ??

I'd just start stepping back versions to determine if this is a regression from a previous release. I have no particular version in mind, but here is a good stepping progress:

1.4.21.1, if working, move forward from there. If not working, then likely isn't a regression.

If working in 1.4.21.1, then try moving to 1.4.26, if working, then move to 1.4.28, if working, then is a regression between 1.4.28 and 1.4.29.

OK, reading through the scenario, it basically looks like we're not getting a Busy indication back when C is busy.

I don't have time yet to test previous version. Basically this is the problem, because the hangup is sent but no tone is heard
