You're right. There is some problem with Welltech flash event (don't
or can't send to PBX) I think as well but I hope I was wrong. I tried
my config without Asterisk and directly connect ATA-151 (bureau mode)
with 3802 (hotline mode). Same problem. Then Asterisk came in picture
because we use 5 of them successfully (just massive memory leaks in
interactive mode and need reboot every 2-3 hours).

Thanks for your answer! I happy with every answer because I don't know
where could I go. I hate Welltech GUI because a lot description/label
is bad and might missleading and there are some parameters you could
adjust only in terminal mode. Documentation is bad as well. But I need
to work with this hardware. I'll do a search on past mails.

Do you know where should I find a list with Asterisk compatible USB
modems/chipsets? We plan putting Asterisk on the PBX side and with USB
modems as Zap channels we could make flash to PBX but I don't find any
list about compatible USB modems/chipsets.

Bye,
