[asterisk-users] problem registering to ekiga.net

[Magosányi Árpád]

  Hi!

I want my PBX to be reachable at my ekiga.net account. It seems I am 
registered:
vajna2*CLI> sip show registry
Host                            Username       Refresh 
State                Reg.Time
ekiga.net:5060                  magwas             585 
Registered           Sat, 13 Nov 2010 13:48:22

However when others try to call magwas at ekiga.net, they find me unavailable.
My asterisk is available when called directly.

(As an aside note, the 
http://www.ekiga.net/status/presence.php?user=magwas shows me as 
available even when I am not registering.)

What could be the problem?

my sip.conf:
[general]
context=default                 ; Default context for incoming calls
srvlookup=yes
;videosupport=yes
allowoverlap=no                 ; Disable overlap dialing support. 
(Default is yes)
realm=patyicivil.local          ; Realm for digest authentication
bindport=5060                   ; UDP Port to bind to (SIP standard port 
is 5060)
bindaddr=0.0.0.0                ; IP address to bind to (0.0.0.0 binds 
to all)
externip=188.36.152.83
srvlookup=yes                   ; Enable DNS SRV lookups on outbound calls

register => magwas:mypassword at ekiga.net
registertimeout=20             ; retry registration calls every 20 
seconds (default)
