Port Forwarding for presence on Android & Windows

[verta]

Hi All,

I've just installed 3CX PhoneSystem v12 for the company I work for. I'm having an issue with 3CXPhone for Android and 3CXPhone for Windows whilst out of the office.

First off, my issue with Android.

When our Android phones are out of the office, 3CXPhone for Android will connect to our 3CX PhoneSystem just fine for calls (via port 5060), however we get "Connecting..." stuck in the top left hand corner of the softphone, and we are unable to get any presence information or call history. Does this require additional port forwarding like the 3CX MyPhone did?

Now, my issue with 3CXPhone for Windows.

Whilst out of the office this will simply not connect, it comes up with the message that the 3CX PhoneSystem isn't available, however in the Accounts settings, the out of office IP & port are correct - I'm unable to click the icon to select office/out of office to change between modes though. Is this because it's in CTI mode? Is there a way to get it to switch to softphone mode whilst out of the office?

FYI, the Firewall Checker passes just fine - ports 5060 TCP & UDP, 5090 TCP & UDP and 9000-90049 UDP are statically mapped.

EDIT: I've ran Wireshark whilst opening 3CXPhone for Windows with the "Out of Office" selection in Accounts ticked and it's trying to connect on TCP Port 5000... this isn't mentioned anywhere in any tutorial, training video or the 3CX PhoneSystem v12 manual - is this correct?

Any help is greatly appreciated.

Kind Regards,

Verta.

Yes. MyPhone and other components use the web platform.. port forward 5000 TCP accordingly.

EDIT: I've ran Wireshark whilst opening 3CXPhone for Windows with the "Out of Office" selection in Accounts ticked and it's trying to connect on TCP Port 5000... this isn't mentioned anywhere in any tutorial, training video or the 3CX PhoneSystem v12 manual - is this correct?

As previously mentioned, presence/admin/provisioning runs on the web platform, thus 5000 TCP.

It's a mixed bag whether or not to forward the port. Clearly if you want these features accessible from outside your LAN, you should. However, to get calls in and out of the system does not require that port be forwarded at all.

Thanks ian.watts, I'll set up port forwarding for TCP 5000 - we do indeed require presence out of the office, I'd have thought this would have been mentioned in the Manual under the 3CXPhone for Android (or iOS) section as it's surely going to catch others out given the amber icon on the main screen of the app!

Cheers,

Verta.

Are you using the tunnel? If using the tunnel my understanding is that you just need port 5090 provided you manually provision the phones. If you aren't using the tunnel you should. Makes the connection much more reliable.

Hi lifeline,

I've tried with and without the 3CX Tunnel enabled, both scenarios don't give any presence information on Android or Windows - we do get telephony though.

 

[ian.watts]

Indeed, the web platform components (presence, management, provisioning, etc) do not tunnel.. only the calls.

do not forget that https is on 5001 if configured!

I'm having a weird issue, when using a tunnel connection

1. I can make/hear incoming call
2. I cannot make/speak in an outgoing call

Caller ID does not work for remote....

I have port forward the following, allowed all options for extensions from the 3CX System
5090
5060
9000 9049
5000

Now the confusing part, the 3CX System at the Tunnel Tab, only gives the IP of the local machine
But to have the tunneling work, I have to enter the Network Public IP at the 3CXPhone

I'm not certain what part is confusing. At the phone end, you have to put in the public IP of the 3CX server (PBX), or a URL. If you don't, how does the phone know where to register?

1. I can make/hear incoming call
2. I cannot make/speak in an outgoing call

You can receive an incoming call at the remote extension?

Have you tried using the remote extension at multiple locations. If it is only at one location there may be an issue with the router there, or a conflict with other devices on the network. Moving it to another location would show whether it is the location, or a settings issue.

Hello,

Thank you for the reply

I have tried it at many different locations, different networks,different extensions, different settings.

Still same problem: Cannot make outgoing calls, people cannot hear you talking

Even internally, within the same network, you can register a phone as outside office and to use the tunnel, and same result, no outgoing, once you switch to inside office, everything works just fine

I have no clue what is going on

I recently used the tunnel at an office before our P2P network was installed.
The phones PBX IP address was actually the internal address.
And for the Proxy, you enter the IP Address of the Tunnel computer on the local network.

Please see the photo attached of my config

I have tried all options, same results, not being able to make outgoing calls, and if someone calls in, they cannot hear me speaking

Once switching to my internal IP, all is going fine!

I have forward the following ports, disable SIP ALG,
5090
5060
9000 9049
5000

Does this have to do with something at the outbound rules settings?

 

[craigreilly]

ahh - softphone, right.

Is 10.0.0.4 where the tunnel software is running?

 

[tarmeeb]

Yes it is

I have downloaded the SIP Proxy Mangment

Same thing

Maybe,it has to do with the Gateway setting? Cisco 3102

 

[tarmeeb]

Now the firewall check says port 9014 and 9032 are not opened

Although I have done the forwarding for 9000-9049 UDP

 

[craigreilly]

Firewall on local machine?
AntiVirus blocking ports on local machine?

Can you give me a clearer layout of your network?
Phone System local IP:
Proxy Server IP: 10.0.0.4
Remote Network IP Scheme:
3cx Server/Office Network IP Scheme:

High,

I have run the host PC (3CX System side) and client PC (3cxSoftPhone Side) both on VPN, same result

My PC where 3CX System is installed : 10.0.0.4
My Router Gateway is : 10.0.0.1
My SPA 3102 is : 10.0.0.100
My Router Public IP : Lets just assume 888.8.8.800

Now Computer where soft phone is installed:
PC where 3CX Softphone is installed : 127.0.0.150
Router Gateway is : 127.0.0.1
Public IP : Lets just assume222.2.2.200

Not sure how this might help? My network structure?

1. PBX Side (where 3CX Sys is installed)
a) A router with public IP : 888.8.8.800 and local IP 10.0.0.1
b) SPA 3102 IP: 10.0.0.100
c) Computer where 3CX is installed and Tunnel 3CX IP is : 10.0.0.4

Now I have tried remote extension on Androind and Windows Machines

Same thing > incmoing calls are fine, you can hear voice, shows CID
outgoing to even internal ext : Not happening
hearing someone's voice : Not happening

All options for Ext are checked-unchecked to allow it receive/send calls outside LAN

I have tried using SIP proxy manager by 3CX, same result.

Actually I have a question for you, do you have a copy of a backup files for a 3CX config files working fine?Maybe I am missing something with the config?!!! Or it has to do with the SPA3102 config itself?
