HELLO & WELCOME

Hi,

I wonder if anyone here has had similar issues to me with incoming calls on PSTN (Obiline) answered by an extension to FreePBX off the PH1 interface on the Obi202 being disrupted by intermittent DTMF dial tones?

Any help would be appreciated

• There is a SIP trunk from the Obi to the FreePBX (RasPBX) all on the same gigabit switch.

• PSTN is a virgin media line.

• Incoming calls to other extensions on the FreePBX do not appear to have this problem.

Setup similar to this:

SIDE NOTE:

I also have distorted choppy audio if I connect the ObiLine through USB (AC powered) hub with my ObiBT USB adapter.

Hi,

Did you find a solution to this problem? I am having a similar experience on my Obi202. It only affects the PSTN line coming throught the obiline adapter. Calls using either Obitalk or Voipfone are not affected. It sounds like the first two tones from an old dial up modem. There is also echo of the ring tones.

It happens at the point when the call is passed back from Freepbx to the Obi:

Code: Select all

Any thoughts Anyone?

TIA

It might be what's known as "talk-off" where the device is interpreting the voice as a DTMF digit.

I will try and replicate this tomorrow...

Hi Paul,

Any luck?

As a thought: my freepbx was on the WAN side of the Obi - so Ithought moving it to the LAN port might make a difference, so i changedit over today, but in the event it made no difference.

What version of freepbx are you guys using?

[Echo44]

Hi Paul,

I am using Raspbx which has:

Freepbx:
Asterisk: 11.18.0
Freepbx: freepbx-2.11.0beta1
The Obi202is:
HardwareVersion: 1.4
SoftwareVersion: 3.0.1 (Build: 4822)

HTH

[WelshPaul]

I did test this out with RasPBX running the following versions...

Asterisk (Ver. 11.18.0)
FeePBX 2.11.0.43

OBi202
Hardware Version 1.4
Firmware Version: 4822

I didn't encounter the issue mentioned in this thread. Tested using a Virgin Media telephone line with the OBi202 configured with the U.K. Configuration.

I see your running 2.11.0beta1, try updating your FreePBX and report back.

[nebs]

FreePBX 12.0.76.2
Asterix 11.18

OBi202
Hardware Version 1.4
Firmware Version: 3.1.0 (Build: 4972)

Still having problems with any incoming mobile calls via Virgin PSTN going silent if they go through trunk to FreePBX. Calls that stay on OBi are fine.

Hi Paul,

Tried updating with raspbx-upgrade. That didn't make any difference. However, I have a Pi2 on the way so will try a completely fresh install later this week.

Sorry I have not posted back, I have been extreamly busy with work and family life as of late.

I did setup a test environment but wasn't able to reproduce the problem, not saying it doesn't exist as I know the OBiLINE adaptor works for some and is extremely problematic for others.

Did you guys get anywhere with this?

[nebs]

No I still have the same problem if an incoming call from a mobile and it goes through a trunk from the Obi202 to FreePBX it will generate a sporadic DTMF tone which will cause the line to go quite.

I have tried two different PIs and also a virtual machine (VMWare ESXi) running FreePBX.

Still no joy!

The setup I have is an Obi202 with a powered USB hub with an OBIBT and an OBILINE plugges into it.

I will try without the hub and see if problem still exists, it is not the Obi202 as Obihai replaced it, still same problem.

I have had the problem occur on a call from NZ as well.

Outgoing calls are OK. Even if they originate on the PBX from a Cisco 7960 extension.

It is a real pain, I am wondering if it is a mistake with the trunk setup?

[Echo44]

Further update:

Replaced original Pi with Pi2:

Now:
Freepbx:
Asterisk: 11.20.0
Freepbx: 12.0.76.2

The Obi202is:
HardwareVersion: 1.4
SoftwareVersion: 3.0.1 (Build: 4822)

But the tone problem persists.

I'm now 100% VoIP and don't have any access to a PSTN line anymore.

Have any of you tried replacing the OBiLINE adaptor?

I was also thinking, maybe you could disconnect the PSTN line from the 202 and setup a second ATA and connect that to the 202 as a fake PSTN line? See if the issue occurs that way?

If your interested... I have some OBi110's sitting here in a box that I plan on giving away in future competitions - I can send you an OBi110 in the post (if you pay the postage of £3.90)? You can then swap out the 202 with the 110 and see if the issue remains? Would rule out the PSTN and FreePBX as being the cause? Your welcome to keep the OBi110. :)

Let me know...

[Echo44]

Hi,

Yes if you could send me a 110 to try tht would be excellent, as I am beginning to suspect that the obiline is the culprit as there is no problem with either the voipfone interface or obion from my smart phone.

What is the best way to pay the postage?

Thanks

Will drop you a PM with my paypal address, will ship it to you in the morning. Hopefully will be with you Saturday AM! Reply to my PM with your name and address...

Also try using your existing 202 cables with the OBi110 at first as that should also help rule out an existing cabling issue.
