Outbound calls failing from 3CX to Skype

[almefab]

Hi,

We have 3CX set up and everything is working fine with the PSTN Lines. We are now setting it up with skype using 3CX Gateway for Skype.

Everything on the 3CX Gateway for Skype software is up and registered also configured with skype logged in, showing balance etc, from 3CX Phone System the Skype Gateway is also registered.

Also just to let you know that 3CX Phone System and 3CX Gateway for Skype are on the same machine with ip 192.168.0.127 (entry is in host file aswell to make it available from localhost)

So we have an outbound rule for Skype Gateway to press 3, 00356 is the area code i'm calling and 79xxxxxx is the number trying to call.

When i try to do an outbound call from a 3CX softphone or any other phone connected to VOIP adapters we are getting the following errors:

Error on 3CX Phone System:

15:43:47.015 [CM503008]: Call(82): Call is terminated

Hi, Fabian

According to the logfile you posted, the outbound call is closed by Skype side
15:43:46:968 - Info : Call (skypeid 2061) has been ended by Skype
on such "answer" gateway closes PBX's call with "busy here", what you saw.

I've done a test similar to your issue, I've got the same result, then I've tried to call the same number from standalone Skype client and I've got what you see below:

Vali,

First of all thanks for your promp reply.

I have tried again to call from a skype client the same number 0035679xxxxxx and successfully worked.

I can confirm that i have skype credit and everything from a normal skype client works fine.

Regards,

Fab

 

[Vali_3CX]

:roll: mmm, ok, I will try to find the reason, and will tell you if I will have some news

Thank you for your feedback

vali

 

[almefab]

Thanks Again,

To be honest it worked twice, i've changed the setting in the screenshot attached which can be found in the 3CX Phone System under PSTN Lines of the Skype Gateway and managed to call twice, but stopped working after a few minutes.

I don't know if that had anything to do with it but thought it might help you.

Regards,

Fab

I'm almost 100% sure is not related - this setting affects gateway' registration to PBX, therefore the "SIP side". If from various reasons this registration fails, your outbound call won't be able to "reach" the gateway - or the logfile shows the SIP side is perfectly OK.

When we designed the new gateway, we had in mind three rules: easy to configure, never get stuck (and/or always be able to recover itself, set it, start it and push the machine under your desk) and provide user enough information (not too much, but not too less) to don't let him to get lost. It seems we still have to work :mrgreen:

That's why there are users like us who try a free product and test it out so you can make it better everybody gets something from each other hehe. If you need something else to try and figure out the problem just let me know.

I still don't know why it worked for about 3 calls after don't know how many failed attempts and suddenly stopped again

Hello Fab, Vali,
I have the same issue where outgoing calls through Skype fail. I'm using the latest version of 3CX and Gateway monitor. The Gateway monitor show the Skype ports as registered and on hook. The call is routed to the Gateway but goes no further, returning busy. I can dial outgoing calls directly using Skype so that is set up correctly. As with the log that Fab attached, the key entry appears to be -"17:01:23.273 [CM505002]: Gateway:[Skype2] Device info: Device Not Identified: User Agent not matched; " It doesn't appear that the 3CX phone system is associated itself with the Gateway Monitor?

Have you been able to get this scenario working?

Thanks
Chris

Hi, Chris

According to the logfile you provided, the configuration you've set seems to be OK.
Since I don't have the logfile of the gateway port which answer "busy", I assume the most possible reason: the port answering "busy" is the master one and you have at least two gateway ports defined.

If this assumption is correct, then the busy status is normal: the master port is designed as the "dispatcher" of inbound calls, therefore gateway cannot afford to reject these calls due to a single outbound one. So, any outbound call to the master in such configuration will be rejected as busy, not even attempting to "touch" its Skype. A master will accept an outbound call only when is the only port in the gateway. Otherwise, the only solution is to configure the gateway with no master port.
If this explanation doesn't help you, please provide me the tracelog of the port answering "busy" (after it answer busy, on Monitor select it and choose, from right-click menu, Tracelog option).

Regards
vali

Hello Vali,
Thanks for the quick response. Now I understand the reason for the Skype master port.
I have two Skype ports created, portID 10011 is the master on SIP port 6060 and portID 10012 on SIP port 6062. The 3cx trace tells me that the Skype Gateway is not identified which I don't understand.

Routing over the 10012 port I get the following trace:

What does a completed call trace look like?

Hi again, Chris

To start with the issue - the reason is there, in the emphasized line: it means the phone number which Skype has to call is not recognized as a valid phone number neither as a Skype account. You may got such kind of error if you try to dial from your phone, for instance, 7101 (7=outbound rule). In your case, I suppose the reason is the phone number you dialed miss country code (I see 0127...., not 00xx0127...). Try to open a standalone Skype and call from there these two "versions" of numbers.

About PBX trace - from my experience "Device Not Identified: User Agent not matched" I saw already many times and I consider it harmless, but I will ask my teammates for a precise explanation.

Hello Vali, introducing the international codes into the outgoing route has enabled the call - drops out on completion but that'll be a different issue. Many thanks for pointing me in the right direction.

Hi Guys,

Is there any update on this. I am a newby in 3CX potentially interested in a software PBX (or hosted environement) for my org. Dealing with Skype is a must have and I am confronted with the same issue on a complete new install (Win x64 Vista Ultimate). Same log messages.......(busy or not avialable depending upon config settings, but not a working system and I do have credit on my account )/

Regards,

Rob

 

[Robbie1969]

Ok got it working as I indeed need to dial the international prefix for all numbers. As the next step I am facing the issue that when I am connecting with a voip phone on 1 computer to for example my regular PSTN home phone using Skype the connection is made without difficulties. However it also connects to my other VOIP phones on different systems.... any ideas?

Cheers

Rob

Hi, Rob
I'm not able to "get the picture" of the configuration you describe. Please try to describe it a little more precise, "phone A, phone B, PBX, gateway, outbound rule" and so on.

i had the same exact problem. you need to dial the country code for some reason. So for your outbound rule, use your 3 to select the line, strip 1 digit, and prepend your country code. For me it is 001 (USA) then you can dial anywhere in the US or when you dial just remenber to enter the country code.
