Hi, guys. It’s my first time working with Asterisk and I’m facing some problems.

Softphone 100:
Account Name: 100
SIP Server:
Username: 100
Domain:
Login: 100
Password: senha100
Display Name: Vegeta
Voicemail Number: 500

Softphone 200:
Account Name: 200
SIP Server:
Username: 200
Domain:
Login: 200
Password: senha200
Display Name: Kakaroto
Voicemail Number: 500

I’m trying to call 100 from Vegeta, but I always get this error:
[Oct 23 11:20:46] WARNING[3776][C-0000000b]: pbx.c:2925 pbx_extension_helper: No application ‘VoiceMail’ for extension (INTERNO, 100, 2)

What’s wrong? My Asterisk settings are:

sip.conf:
[general]

srvlookup=no
udpbindaddr=0.0.0.0
tcpenable=no
canreinvite = no
dtmfmode=auto
