Configuring Apple Push to Wake up Your iPhone

This guide applies only for 3CX Phone System 12 and 12.5.

Configuring Apple Push


Step 1: Configure 3CX Phone System for Apple Push Notifications

Step 2 - Enabling Extensions for PUSH

Step 3 Firewall Configuration


3CXPhone uses PUSH technology to wake up the smartphone when a call is received. This does not require the user to keep the phone active to be able to receive calls – the phone can go to sleep mode to save battery life.

Note: 3CX Phone System V14 users do not need to perform the following steps as Apple Push is now integrated and enabled by default for extensions

Step 1: Configure 3CX Phone System for Apple Push Notifications

  1. Login to the 3CX Management console
  2. Navigate to “Settings” > “PUSH”
  3. In the ‘Apple Push Notification Server Information’ section of the tab check the ‘Enable Push Notifications’ option

Step 2 - Enabling Extensions for PUSH

After you enable Apple push notifications  you will need to select for which extensions PUSH functionality will be enabled.

To do that move to the “Select 3CX Users” section and select from the left column (that lists your extensions) which ones you would like to enable PUSH functionality for. Click “Add” to add them to the list of PUSH enabled extensions.

Press “Apply” to save your settings and to enable the selected extensions to use PUSH functionality. It might take some time to save depending on the number of extensions you have. Also  keep in mind that you will need to reprovision your iPhones after enabling these settings.

Step 3 Firewall Configuration

Push providers, iOS devices, and Mac computers are often behind firewalls. To send push notifications, you will need to allow inbound and outbound TCP packets on port 2195. To reach the feedback service, you will need to allow inbound and outbound TCP packets on port 2196. Devices and computers connecting to the push service over Wi-Fi will need to allow inbound and outbound TCP packets through port 5223.

The IP address range for the push service is subject to change. The reason being that providers will connect by hostname, rather than IP address. The push service uses a load balancing scheme that yields a different IP address for the same hostname. However, the entire address block is assigned to Apple, so you can specify that range in your firewall rules.

    For version 12.5. Apple Push allow 3CX extension to received call directly or still open tunnel app first?

      Hi Spring, 3CXPhone V14 has the tunnel app built in to the client. There will be no need for separate tunnel app. V12.5 is still the same as it was.

      Thanks for your reply. so it is mean that version 12.5 i cannot received call while my phone is in sleep mode because i just got the notification when there is an incoming call but i cannot answer because to make 3cx for iphone onhook i have to open tunnel and connected it first. every time i got an incoming call i got notification and have to call them back after i connected tunnel.

      Hi Spring, You can choose when to use the tunnel, it is not compulsory. You only need to use it if there is a problem with the call or you are in an environment which is blocking port 5060. If you do need it and you have to use it then up the time in your extensions forwarding rules “Available” tab, “If the call is not answered within field”, to a time that it takes to open the tunnel and answer the call.

  4. Hello,
    I cannot enable Apple Push Notifications. When I go into my 3CX server mgmt console > Settings > 3CXPhone: the “Enable Push Notifications” checkbox is gray’d out and I cannot check it. Also, I have no certificate for the certificate path and I do not know where to get this. Please advise.

    Is the information about removing users from push backwards? v14 SP1 seems that all suers are automatically in (LEFT SIDE) unless specifically removed (RIGHT SIDE).

      @Craig, Removing the extensions that you don’t want Push for from the left box to right manually will disable Push notifications to those extensions.

    Can you clarify the statements about the firewall requirements. I assume that the firewall needs to allow a statefull connection from the IOS device making a connection out of the protected environment to the Apple push servers on either port TCP 2195, 2196 and or 5223 (the statefull nature allowing the return traffic)? Or are you saying that we need an inbound NAT and firewall rule to pass this traffic to the 3cx phone server as well?

      @Jonathan, thanks for the question. These ports are required to be allowed out of the network. If you allow all traffic outbound then these ports can be ignored from the firewall checker results.

      We can’t get the PUSH for iPhone to work (Android works fine). When I use a network sniffer on the (remote) server where 3CX runs, there is no activity on TCP-ports 2195, 2196 or 5223. So I wonder whether I should investigate the firewall. Might there be something wrong with my versie 14 installation? The PUSH is enabled for all users.

      @Erik, thanks for the question. Would it be possible for you to open a support ticket with us so that one of our support staff can investigate this further for you. Please contact your 3CX reseller /partner to open a ticket on your behalf if you do not have a support contract with us.

  8. I just installed the SP2 to my 3cx server. How can I enable push for iPhone – this option is missing in PUSH website of management console after update!

      Hi, thanks for the question. Push is enabled for all extensions by default. The push setting itself can now be found under each of the extensions settings ‘3CXPhone’ tab.

    I am having problem with PUSH. I have configure push using google cloud. I can see push mode activated on my devices but once my device is in locked mode I cant call in. The call is send straight to voice mail. I thought PUSH was meant to wake up the device. But when I unlock my phone the call come through.
    How can i solve this problem.

      @Ayoyemi, please check that have also enabled the Push for smartphones setting within the extensions settings ‘3CXPhone’ tab. Also if you set up the Google API configuration after you sent out the welcome email to provision the phone using the config file, then you need to resend the welcome email and provision again.
