Call is dropped against GSM phone

Hi!

I’m absolutely new with asteriks but i think this is great.
I’ve just installed (latest 1.4) onto my Fedora box.
No config are changed but 2 test user setup [marxye61] for calling from my gsm phone and [test] for calling from my PC.

The first thing i got that when i call from PC all things are good.
I called 500 demo number and users from out of my site (for. ex. ekiga.net)

But when i try to call demo phone 500 from the phone asterix (or phone) drops the call. Phone writes that call was 0:0:0 long. I think that there was no call time at all.

I turn on sip debug for my phone call and got no intersting lines.
Nothing in the debug log contains any error message I expected to see.

I think all this seems like codec issues, isn’t it?
This is a logic 'cause my PC calls works good.

BTW, when I tried to call from PC to my gsm phone i got the invite on my phone. But when i tried to answer i got no sound in the tube. Just a silence.

Any help will be appreciated!

Updates:

i ve just call to my side from the home using gizmo account.
all auto answer services (500, 600, 2) are worked nice. No call
drop. So, as i supposed above something wrong with the settings
of my asterisk server. But i don image which one… :frowning:
