Requirements

Python 2.7.3+ with SSL support is required.

Request Access Token for a Trusted App

Code Block

language	py

import httplib
import json

# Modify these values with the ones you intend to use
VN_SERVER_ADDRESS = 'CHANGEME'
APP_KEY = 'CHANGEME'
APP_SECRET = 'CHANGEME'
REDIRECT_URI = 'https://' + VN_SERVER_ADDRESS + '/ouath/token.php'
TYPE = 'unifiedapi'
URI = 'https://' + VN_SERVER_ADDRESS + '/oauth/token.php' 

# Setup the requests parameters
headers = {"Content-type": "application/x-www-form-urlencoded"}
content = "&client_id=" + APP_KEY + "&client_secret=" + APP_SECRET + "&grant_type=client_credentials&type=" + TYPE + "&redirect_uri=" + REDIRECT_URI
conn = httplib.HTTPSConnection(VN_SERVER_ADDRESS)
conn.request("POST",URI, content, headers)

# Parses the JSON response
response = conn.getresponse()
print json.dumps(json.loads(response.read()), indent=4)

This request will have the following output:

Code Block

language	py

{
    "access_token": "1|W-rhVICLEV-NsP3AAEN-mNCDEBHz-7bf|1|1402415213|x-5nQMXISV_XGTS6Yg2_kOB2TNnH_S0d",
    "token_type": "Bearer",
    "expires_in": 7200
}

Make a Call Between Two Public Numbers

The example below demonstrates how you can use Unified API to connect two public numbers, not registered with VoipNow. It uses the Create Simple PhoneCalls request.

Code Block

language	python

import httplib
import json

# Modify these values with the ones you intend to use
VN_SERVER_ADDRESS   = 'CHANGEME'
API_ACCESS_TOKEN    = 'CHANGEME'
EXTENSION_NUMBER    = 'CHANGEME'
PUBLIC_NUMBER1      = 'CHANGEME'
PUBLIC_NUMBER2      = 'CHANGEME'

# Setup the requests parameters
data = {
    "extension": EXTENSION_NUMBER,
    "phoneCallView" : [{
        "source" : PUBLIC_NUMBER1,
        "destination": PUBLIC_NUMBER2            
    }]
}

headers = {"Content-type": "application/json", "Authorization": "Bearer " + API_ACCESS_TOKEN}

# Makes a HTTP POST request using SSL
conn = httplib.HTTPSConnection(VN_SERVER_ADDRESS)
conn.request("POST", "/uapi/phoneCalls/@me/simple", json.dumps(data), headers)

# Parses the JSON response
response = conn.getresponse()
print json.dumps(json.loads(response.read()), indent=4)

Make a Sandbox Call

Unified API can be tested using the Sandbox numbers. The example below uses the Create Simple PhoneCalls request to make the call.

Code Block

language	python

import httplib
import json

# Modify these values with the ones you intend to use
VN_SERVER_ADDRESS 	= 'CHANGEME'
API_ACCESS_TOKEN 	= 'CHANGEME'
EXTENSION_NUMBER    = 'CHANGEME'
SANDBOX_NUMBER 		= 'CHANGEME'

# Setup the requests parameters
data = {
	"extension": EXTENSION_NUMBER,
	"phoneCallView" : [{
		"source" : EXTENSION_NUMBER,
		"destination": SANDBOX_NUMBER			
	}]
}
headers = {"Content-type": "application/json", "Authorization": "Bearer " + API_ACCESS_TOKEN}

# Makes a HTTP POST request using SSL
conn = httplib.HTTPSConnection(VN_SERVER_ADDRESS)
conn.request("POST", "/uapi/phoneCalls/@me/simple", json.dumps(data), headers)

# Parses the JSON response
response = json.loads(conn.getresponse().read())
print json.dumps(response, indent=4)

Park a Phone Call

Anchor

	demo-ph-park
	demo-ph-park

Transfer a Call to a Public Number

Anchor

	demo-ph-xfer
	demo-ph-xfer

The example below demonstrates how you can use Unified API to transfer a call to a public number, not registered with VoipNow. It uses the Transfer PhoneCalls request.

Code Block
