Issue with Patton SN4114/JO VOIP gateway

ahmedsallam · October 26, 2023, 6:00am

Good Morning Colleagues
I hope you are doing well . I have successfully configure Trunk between FreePBX and Patton FXO SN4114/JO VOIP gateway . Calls working as expected. The topology as follow:

Customer/Caller ==> Telco ==> Patton SN4114/JO ==> FreePBX ==> Queue ==> Agents

I have only one issue with Patton

When a call received from a customer/caller and if the customer/caller disconnect/hang-up the call from his end before an agent has the chance to pick-up the call , The call continue to ring until an agent pick-up the call and once done , The agent hear the disconnect tone and the agent has to close the line from his side.

I tested another gateway from another vendor and this issue doesn’t exist .

May I know how can I solve this issue in Patton SN4114/JO VOIP gateway ?

Best Regards

The end of the call is not detected. That can happen. You probably need to look at the configuration of the Patton device. I actually use some of these gateways myself, but never had the problem you described.

I just checked one of my SmartNode ATAs and didn’t find any specific settings. You probably want to look at SIP traces to find out where the problem is. I remember that I once hat a problem with using a DTMF sequence that was also used by the (Grandstream) ATA. So there might be not so obvious problems.

Hello ig
DO you think the issue could be with tone set ?

Since Patton didn’t detect the end of the call , Does this mean that the tone set configured at Patton not match with remote disconnect tone used in Egypt ? Do you think this could be the reason ?

Best Regards

I don’t like to speculate. If it’s a problem that can’t be solved immediately, I try to forget what else it could be a solution. Instead, I have my own extensive testing procedures that start with the hardware. I have already rejected customer orders where they said it was all too time-consuming.

Sometimes your own bias obscures the usually trivial cause. I still have a few points that could be quickly clarified beforehand, but I’d rather keep my mouth shut.

Good Afternoon Colleagues
I hope you are doing well . The issue has been solved by using the below tone profile compatible with Egyptian PSTN:

profile call-progress-tone defaultDialtone
flush-play-list
play 1 1000 425 -6

profile call-progress-tone defaultAlertingtone
flush-play-list
play 1 1000 425 -13
pause 2 4000

profile call-progress-tone defaultBusytone
flush-play-list
play 1 300 450 -7
pause 2 300

profile call-progress-tone defaultReleasetone
flush-play-list
play 1 300 450 -7
pause 2 300

profile call-progress-tone defaultCongestiontone
flush-play-list
play 1 300 425 -7
pause 2 400

Best Regards
