Restcomm outbound call to DID registered at Nexmo

What is the proper way to initiate an outbound call from the Restcomm server to a DID/PSTN phone?

I have a Nexmo number provisioned
Inbound calls work

I have tried this curl command to initiate an outbound call

curl -X POST http://[account sid]:[auth token]@[restcomm server ip]:8080/restcomm/2012-04-24/Accounts/[account sid]/Calls.json -d "From=sip:[number provisioned at Nexmo, e.g. 12125551234]@sip.nexmo.com" -d "To=sip:[my number, e.g. 12125551234]@sip.nexmo.com" -d "Url=[source of xml]"

The result is this log entry:

Call SID [call sid removed]
From [The Nexmo number--removed]

To [My number--removed]

Solution

@Mattias,

In order to use restcomm for outbound calls with Nexmo, you need to update the restcomm.conf file

Go to $RESTCOMM_HOME/bin/restcomm/restcomm.conf

Edit the Outbound proxy as shown below. Restart Restcomm. This will tell restcomm to forward all outbound SIP calls through Nexmo.

# Address for outbound calls
OUTBOUND_PROXY='sip.nexmo.com' #Provide port if different than 5060
OUTBOUND_PROXY_USERNAME='NEXMO_KEY'
OUTBOUND_PROXY_PASSWORD='NEXMO_SECRET'

Are you familiar with creating an RVD Voice App?

I will suggest that you use a SIP phone to make a call to the Destination DID so that you can hear audio.
