[asterisk-users] Lancom 1722 and Asterisk (i need HELP)

[Thomas Janzen]

Hello,

i have a big problem...

i want to connect my asterisk server to a lancom 1722 device (ISDN/SIP) Gateway.

sip.conf:
[general]
context=default
allowguest=yes
realm=10.1.1.209
bindport=5060
bindaddr=0.0.0.0
tos_sip=cs3      ; für SIP-Pakete (Kommunikationsaufbau)
tos_audio=ef     ; für RTP-Audio-Pakete
tos_video=af41   ; für RTP-Video-Pakete
allow=all
dtmfmode=rfc2833
canreinvite=yes

[3000]
type=friend
secret=3000
qualify=yes
host=dynamic

[lancom]
type=friend
context=fax-in
secret=1000
username=1000
fromuser=1000
port=5060

i added a sip-line in my lancom, but it doesn't connect. does anybody know how to configure it??

would be nice, if somebody have experience with lancom and asterisk.

when i create a call with asterisk to lancom, this message appear:
and-fax*CLI> console dial 1001
