Accessing multiple brokers in a single session

I would like to know if it is possible to access multiple brokers in a single python session using the twisted libraries provided by cTrader. The idea is to get 'tick volumes' from different brokers and aggregate them to build a reasonable volume profile.

If I set up two clients only the latest one receives messages - I suspect it is because both are configured to listen to the same port. I think should be able to work as two different servers communicate via the same port. Any guidance will be appreciated. 

with open("ICMarketsDemoPriceConfig.json") as configFile:
    config = json.load(configFile)

client1 = Client(config["Host"], config["Port"], ssl = config["SSL"])
# Setting client callbacks
client1.setConnectedCallback(connected1)
client1.setDisconnectedCallback(disconnected1)
client1.setMessageReceivedCallback(onMessageReceived1)
# Starting the client service
client1.startService()

#twp.writePriceDataDump()
# you can use two separate config files for QUOTE and TRADE
with open("skillingDemoPriceConfig.json") as configFile:
    config = json.load(configFile)

client = Client(config["Host"], config["Port"], ssl = config["SSL"])
# Setting client callbacks
client.setConnectedCallback(connected)
client.setDisconnectedCallback(disconnected)
client.setMessageReceivedCallback(onMessageReceived)
# Starting the client service
client.startService()
