Calls do not hang up

[ChameleonPaul]

Hi.

Yes - I am a 3cx noob...

Have just downloaded and Installed the free 3cx Voip PABX. Is early days... Playing with config / setup...

Our ISP is Exetel (australia http://www.exetel.com.au) – not listed, supported or tested so if have any advice on setup re exetel – much appreciated.

All seems fine so far – can make outbound calls. But they won't hang up. 3cx soft phone or x-litesoft phone, hang up – show hung up. Check status in 3cx server manager – shows call terminated – but it isn't – is still connected... Need to resolve this.

Another – 3cx assistant times out in loggin attempt to server.

Plan is to have inbound calls to 4-5 softphones(extensions), and later fax phone and pstn via ata.

Any tips suggestions gr8ly app.

You might want to post a 3CX log of an outbound call from a point during the conversation to a point after you have hung up but the trunk is still held up. It could shed some light on why the call isn't dropping.

Hi.

Thanks for you reply. Sorry about the late reply - got tasked on other duties for a while.

Behaviour seems intermittent, but frequent enough to be a concern. Log below shows behaviour when a call is made to a Cell phone (mine on desk next to me). Mid call attempt, the call is terminated our end via 3cx soft phone. Call does not hang up - cell continues ringing. Attempt call again - get diverted to voicemail by cell as is still engaged with previous connection. Same for follow ups - repeated trials

In log below, call did terminate after a time. However at other times the call did not terminate.

I have tested it and the call has hung up on terminate via soft phone. but is less frequent than not hang up.

Any clues?

Log follows.

Further Info.

I tested with an x-lite soft phone via other voip did account to same cell, same voip provider, independent of the 3CX gateway. In all cases calls terminated when initiated from softphone.

Further - direct call via x-lite makes connection/ringing almost instantly. Call via 3cx soft phone via gateway and there is significant lag/time taken to establish connection/ringing. [correction: this may be perceived - not actual. 3cx gives dial tone/ringing tone immediately and can hear when connection takes place as second overlay ringing tone occurs. With the x-lite there is slience until connection is made and then only 1 ringing tone is heard].

So problem appears to be termination via the 3CX voip gateway and/or config - setup.

Any clues / advice?

The No RTP packets received usually indicates that some of your ports aren't opened or a firewall could be causing an issue. It's probably NOT a good thing in any case.

In the 3CX softphone you can change the option to suppress the "false" British style ringback tone, it can be misleading but some people like to have a RB tone immediately after they dial.

Mid call attempt, the call is terminated our end via 3cx soft phone. Call does not hang up - cell continues ringing.

What happens if you hang up AFTER the called party has answered? Does the call drop immediately then? Have you tried calls to other numbers besides your mobile? Is there a two way voice path? What about calls to a land line where you hang up and the called party is still ringing?

There have been posts involving some VoIP providers not sending the expected (proper) messages and this could be the case. You may have to "Wireshark" the LAN connection to show more detail about what SIP messages are and aren't being passed between 3CX and your VoIP provider.

Hi.

Thanks for your reply.

I'll investigate the ports on the server. I tried the firewall checker... I do not have rights to that server (stop services etc)- will need to arrange rights to proceed.

Re the suppress false british style playback tone - where do I find this option? - looking but not found yet...

Re the calls and testing - it did seem to only occur if the call was not answered and we terminated at our end and then re-tried. I tested to another voip number (different provider) with same result. On pick up there is a 2 way voice path - we can make calls etc, it is only the hang up issue... I'll try to arrange further tests to fixed pots landline number and compare no answer vs pick up.

If we go down the track of wireshark - what packet (proper message) would I be looking for?

FYI: appears to be very little on 3cx in our voip providers forums... (Exetel).

Cheers,

Paul
PS - I love this product and can see huge potential for it - so am keen to 'get in to it' ...

Hi. One more bit of information:

DTMF tones do not appear to be OK. Call a service with digital operator, press tones are ignored/fail particularly #... Any clues (am also looking through the forums).

 

[ChameleonPaul]

Hi.

Just trialled x-lite softphone (at defaults) on 3cx pbx... Guess what - no issues.

Call terminated as expected;
No false British tone;
Appeared to connect quicly..

(So issue is with 3cx soft phone client??)

Have not tested with 'press 1 for...' services yet.
