In the relevant part of your Asterisk "extensions.conf"
insert the following lines:
exten => Inbound_Number,1,Dial(SIP/201)
This will normally need to go in your [default] context unless
you have configured Asterisk to route inbound sip calls from
"sip.freevirtualnumbers.co.uk" to another context.
Please note that Inbound_number is the user portion of the destination
you configured (sip:Inbound_number@AsteriskServerAddress), and you should replace
the Dial(SIP/201) part with an Asterisk function to route the call to
your phone or a number of phones. This example assumes
your phone is logged into your Asterisk server as extension "201".
If you have purchased a block of numbers, repeat the above for
each number.
Finally, please note that the SIP Forwarder packages allows
INBOUND calls only.
For an easy and cost effective way to make outbound calls from your Asterisk server, you might be interested in our IAX Calling package
Example:
You have purchased 0870 100 100
You have set up the Destination as:
sip:0870100100@81.187.77.256
In the relevant part of your Asterisk "extensions.conf"
insert the following lines:
exten => 0870100100,1,Dial(SIP/201)
