Hello
My provider allows to activate/deactivate a forwarding rule by sending a
SIP MESSAGE. This is done outside a call. That is, while there is no
ongoing call, a SIP client just sends the following message:
MESSAGE sip:[email protected] SIP/2.0
Call-ID: b9ba106e-613a-46b9-8a4d-0efb4dc0a0f2
CSeq: 1 MESSAGE
To: <sip:[email protected]>
From: "543951354657" <sip:[email protected]>;tag=...
Max-Forwards: 70
Supported: 100rel
User-Agent: ProviderX-SoftPhone
Accept: text/plain
X-Movial-Content: application/x-movial-control;forwarding=true
Content-Length: 0
Via: SIP/2.0/UDP 192.168.8.72:5062;branch=z9hG4bK-.....
If successful, the server will respond with a message like the following:
SIP/2.0 200 OK
Call-ID: b9ba106e-613a-46b9-8a4d-0efb4dc0a0f2
CSeq: 1 MESSAGE
To: <sip:[email protected]>;tag=0f315726
From: "543951354657"<sip:[email protected]>;tag=...
Via: SIP/2.0/UDP 192.168.8.72:5062;branch=z9hG4bK...
Content-Length: 0
P-Charging-Vector: icid-value=2ad48aa502d9e80240a5da2efac9029e
X-Movial-DisplayError: false
Basically, to activate the forwarding I need to send a MESSAGE with the
header:
X-Movial-Content: application/x-movial-control;forwarding=true
while to deactivate the forwarding the MESSAGE header must be:
X-Movial-Content: application/x-movial-control;forwarding=false
I have very little experience with AMI and AGI but, from what I've read
so far, neither of them seem to provide any function to send a SIP
MESSAGE with custom headers...
How can I send a MESSAGE like this from Asterisk?
Thanks,
