Provider Configuration: Belcentrale.nl
From FreeSWITCH Wiki
Belcentrale.nl
Incoming and Outgoing works
In conf/directory/default/ (or default) create a file belcentrale.xml:
<include>
<gateway name="belcentrale.nl">
<param name="username" value="31XXXXXXXXX"/>
<param name="realm" value="sip1.belcentrale.nl"/>
<param name="password" value="your_password"/>
<param name="register" value="true"/>
</gateway>
</include>
then in sip_profiles/nat.xml (or default.xml when not using NAT) edit the setting for auth_calls and set to false: <param name="auth-calls" value="false"/>
DTMF does not seem to work with RFC2833. Had to set phone to use in-audio DTMF.
