Galaxy S3 - No incoming or outgoing external calls

[gbschulz]

We are running 3CX Ver 12 with the latest 3CXPhone for Android. We cannot receive or place external calls via the Android. Same results if "in office" or "out of office" using 3CX tunnel. All outgoing external calls terminate on the client with the message "Call Failed, Not Acceptable". Internal (extension) calls received or initiated by the Android work fine whether in or out of office.

By viewing the server log, it appears as if the Android requested the call termination.

Any ideas?

If internal (extension to extension) calls go through just fine, then I would suspect something to do with your outbound rules. You don't have the rules limited to certain extensions, the Android not being one of them, do you?

 

[gbschulz]

We have no inbound or outbound rules that are extension specific. In fact, we only have two outbound rules to route calls to the local POTS or to a foreign line. Neither outbound condition works for the Android but the rules work fine for in-house extensions. Thanks for the thought. Any other ideas?

 

[leejor]

Have a look at the 3CX logs just after trying a call that fails, compare it to a working call from another extension. That should show what the problem is. If you aren't sure what it's telling you, then post the failed call log here in the forum.

Here is the server log when dialing from the Android app (extension 21). The Android IP is 192.168.10.102. The 3CX server IP is 192.168.10.50. The Grandstream gateway is on 192.168.10.51. I have obscured the user name, dialed telephone number, and company name to "ME", "2625551212", and "ABC" respectively. The number dialed matched our outbound rule of a "USA" call.

When I look at the log, it appears to me that the Android app is terminating the call (3rd line down). I welcome your interpretation and advice.

I realize it might be helpful to have the verbose version of the log just before the 10:25:56.036 termination entry. Here is the verbose snippet:

One further update. It appears as if the call from the Android app does briefly go through to the dialed number (it rang once at the destination number) before the call is terminated.

 

[gbschulz]

SOLVED!

It turns out that the Grandstream profile had the "Accept INVITE from Proxy Only" turned on. This prevented the hand-off of the call to the Android app. Turning this option OFF fixed the problem.

I appreciate the help from leejor on the forum.

 

[leejor]

Wow, I'll have to remember that one.

As I don't use the Grandstream gateway(s), that is an option that I haven't seen before, nor do I recall this issue cropping up before on the forums.

Did you manually configure the gateway? If it was auto provisioned, I'm wondering why it was not "set" correctly to deal with your phone.

 

[gbschulz]

That was a default configuration. So Grandstream users be aware!
