This setup is used to dial out from Wengo and to ring a SIP extension on incoming calls. The code is made entirely of excerpts of the configuration files, and need the remaining portions of the files to be useful.
Tested on Asterisk 1.4.9.
Conventions:
PHONENUMBER is your phone number assigned by Wengo
USERNAME is your Wengo username chosen when subscribing to Wengo
PASSWORD is your Wengo password chosen when subscribing to Wengo
EMAIL is your email address used when subscribing to Wengo
First you need to get a 16 characters SIP password (referred later to as SIPPASSWORD) from Wengo using Internet Explorer (or any other browser but you will need to view the source of the XML file)
You’ll get something like this
– <sso vapi=”1″>
<status code=”200″>OK</status>
<user>USERNAME</user>
<userid>USERNAME</userid>
<displayname>USERNAME</displayname>
<password>SIPPASSWORD</password>
<outbound>1</outbound>
<realm>voip.wengo.fr</realm>
– <proxy>
<host>voip.wengo.fr</host>
<port>5060</port>
</proxy>
– <server>
<host>voip.wengo.fr</host>
<port>5060</port>
</server>
</sso>
Then edit sip.conf and extensions.conf
sip.conf
[general]
register => USERNAME:[email protected]/USERNAME ;PHONENUMBER should also work (R1)
[voip.wengo.fr]
type=peer
qualify=5000
fromdomain=voip.wengo.fr
fromuser=USERNAME ; Do not put quotes around the username!
username=USERNAME
secret=SIPPASSWORD
progressinband=yes
host=voip.wengo.fr
realm=voip.wengo.fr
outboundproxy=sipproxy.wengo.fr
outboundproxyport=5060
disallow=all
;allow=g729 ;if you have license
allow=ulaw
allow=alaw
dtmfmode=RFC2833
insecure=very
callerid=”Firstname Lastname” <PHONENUMBER>
context=to-wengo
autocreatepeer=yes
auth=md5
Important: SIPPASSWORD is your SIP authentication password, it is NOT your Wengo account password.
extensions.conf
[from-Wengo]
;For incoming calls
;This extension line will ring SIP extension MySipPhone
;60 seconds then hang up. Modify as necessary to fit your dialplan
;Replace USERNAME by PHONENUMBER or whatever you put in register line above (see R1)
exten => USERNAME,1,Dial(SIP/MySipPhone,60,tr)
exten => USERNAME,2,hangup
[to-wengo]
;For outgoing calls
;Modify as necessary to fit your dialplan.
exten => _0.,1,SetCallerID(PHONENUMBER)
exten => _0.,2,SetCIDName(Firstname Lastname)
exten => _0.,3,Dial,SIP/${EXTEN}@voip.wengo.fr
