Outbound calls from iPhone not working

[Trevor13]

I use the 3CX iPhone app. I can receive calls just fine. When I place a call the call will drop as soon as the person I'm calling answers my call.

Using 3/4G, hotspot Wifi, office Wifi? Internal calls, external, both? Have you looked at the 3CX Activity Log of one of the dropped calls. Did this just start, or never worked? App is up-to-date?

Can you make outgoing calls from your PBX using deskphones or other clients?

First stablish if this only happens with the iOS app, or only to a specific number you call, narrow it down

Thanks for the feedback. I can make calls from my desk phone and web client just fine. I have the issue with any number I call. I just did some testing. I took off Wifi and the receiver will hear one ring and then it drops. I don't hear it ringing from my phone but after about 5 seconds it drops and goes back to the home screen. I removed the iOS app yesterday and reinstalled so I believe I have the most up to date version. This happens with both office and home Wifi. I tested using Wifi for internal calls and the same issue is happening. Thanks.

Did you look at the 3CX Activity Log, for one of the dropped calls?

 

[Trevor13]

Yes, but what am I looking for specifically?

 

[leejor]

The destination of the call, and why it ended. You could always post the call log, "X"ing out part any "sensitive" information (public IP, FQDN, etc.)

Hi Trevor,

What happens if you try to call other extensions then rather than outside numbers?

Can you call your colleagues extensions, or can you call *777 (echo test) and get a call going successfully?

 

[Trevor13]

If I dial an internal extension I can hear my phone ringing and theirs. When it goes to voicemail (their side "picking up") it then drops the call. When I dial *777 it rings once and then drops.

Might possibly be a "no ACK" issue, but just guessing without the 3CX Activity Log. Look at the log, for the messages just as the call is dropped, or, If you don't understand it, post the log.

Do you have the 3CX App working on any other devices?

 

[Trevor13]

When I pull up the 3CX web client I can make outbound calls from it. I only have the 3CX App on my iPhone.

How do I look for the log and where do I go to find it? Thanks for everyone's help!

Hi Trevor,

Ok then I would suggest the following:

1. Run the firewall checker - if it doesn't pass then stop here - you will need to address this first
2. Create a fresh extension, don't change any settings
3. Reinstall the app fresh on your phone, and provision only the new extension
4. Make a few test calls to see if the issue goes away
