[GnomeMeeting-list] Ekiga doesn't stay logged into Asterisk

[Conrad Beckert <conrad_videokonferenz gmx de>]

Hi,
could anyone help me with that: I log Ekiga into my Asterisk Server. (To 
integrate the softphones with my Hardware SIP Infrastructure)

Everything is fine - I can issue and take calls, but after a while Ekiga 
disconnects from Asterisk. The number of registered accounts goes down and in 
the account menu the account showes "disconnected".

If I try to reconnect from the account menu I get "forbidden" or "Registration 
failed" ("Anmeldung fehlgeschlagen") 

This goes on until I close Ekiga and come back. Then in nearly all cases it 
connects automatically and stays like that for the next e.g. 10-15 Min.

This is my configuration:

- 3x Ekiga 
-- 1x remote without NAT - over the Internet directly to Asterisk
-- 1x local LAN without NAT directly to Asterisk
-- 1x behind NAT (Linux router) and then over the Internet to Asterisk
All behave the same - so NAT couldn't be the issue could it.

- Timeout 180 sec (no avail changing it) - too much lets Asterisk loose 
patience.
- Asterisk config: sip.conf (I configure from database - so that looks like 
that - the whole line)

What's wrong - what can I do.

Asterisk generally works- I have no problem at all with my two SIPura 
adapters. They work with not a single interruption since I installed them. 
What a pity Ekiga doesn't :-( Perhaps it is more picky and I have to set an 
option in the Asterisk config - but which one?

Thank you for any hints
Conrad
