Extensions duplicated (using Patton)

[JPElectron]

Hello, I'm using two Patton 4114 boxes for a total of 8 POTS lines. While everything seems to be working fine (from an end-user calling in/out perspective) I'm noticing the virual extensions get duplicated frequently -as if 3CX can't determine a call has ended? I've asked Patton tech support and they said ask 3CX.

This is running the latest version of 3CX, the supported firmware of the Patton boxes setup via the config file generated by 3CX, the server runs Win2K3 and server-to-patton connectivity is via a Cisco switched network.

See screenshots for examples...

So you have 2 Patton 4114's on separate IP's and they were each separately provisioned by a 3CX generated template?
In that case i would change the starting port number on the second 4114 to be 10020 and see what happens.
Also check that you have the correct tonesets and country selected so that the Patton knows when calls have been terminated.

Correct, two devices, seperate IPs.
After first installing we had many problems with line disconnect and hearing a bunch of DTMF tones at the start of a call - but this has since been resolved with Patton and the local telco by 1) increasing the loop-break duration and 2) getting an old fire alarm circuit off of one of the lines (was holding line open after a call, possibly sending DTMF tones)

This is in the US, telco is AT&T, both devices are set as follows...

Tone profile...
Tone Duration = 80 in milliseconds [>40]
Min. Tone Gap = 120 in milliseconds [>40]
Signal Level = 0 in dB [-31..0]

PSTN Profiles...
Echo Canceler [checked]
Hybrid Loss = 6
Non-Linear Processor Mode [checked] [adaptive]
Output Gain = 0 in dB [-31..31]
Input Gain = 0 in dB [-31..31]
...side note, incoming call volume is really soft when compared to the 3CX lady/voicemail system prompts, I tried increasing input gain but then echo was way to annoying - any ideas on a better configuration?

FXO Port config...
Port State [Enabled]
FXO Profile [us]
Flash-Hook Duration = 100 in milliseconds
CID Format [checked] [etsi] ...noticed when unchecked it just comes back again, we don't have caller ID on any lines so I wanted to disable it
Binding [checked] IF_FXO_0

Call router/FXO Interface config...
Call-Routing Destination [checked]
Interface IF_SIP_0
Precall Service [unchecked] (none)
Connect Signals
Battery Reversal [unchecked]
Tax Pulse [unchecked]
Disconnect Signals
Battery Reversal [unchecked]
Loop Break [checked]
Busy Tone [checked]
DTMF [unchecked]
Mute Dialing [checked]
Start Dialing After
[chceked] Timeout = 2 in seconds
Ring Number
[checked] Ring bursts: 1
Loop-Break Duration
Minimum = 200 in [mS]
Maximum = 2000 in [mS]
PSTN Profile [default]
Tone Profile [default]

Model SN4114/JO/EUI
Hardware Version 4.4

...note a discrepancy between the 3CX site and Patton's download page:
http://www.3cx.com/voip-gateways/patton-smartnode.html says "...using firmware 'Smartware 5.3 Build Series 2009-01-15' versions..."
http://upgrades.patton.com/list.asp?model=SmartNode%20411x&flag=1 lists...
Smartware 5.3 Build Series 2009-05-20 (what I'm using cause the version is 5.3)
Smartware 5.2 Build Series 2009-01-14 (closest date to the 3CX desired version, but wrong version)

When you say "In that case i would change the starting port number on the second 4114 to be 10020 and see what happens." do you mean the TCP/UDP port or the virtual extension port?
