Hosted system with SBC and Patton 4112 in office issues

[JohnPhone]

Hi Folks,

We are trying to connect a Patton 4112 for faxing from our printer and a second port to an analog phone line.


Topology:
Hosted 3cx
SBC in office
Patton 4112 in office connecting to SBC on the same subnet
SIP provider is Telnyx

Patton is running

Followed directions from 3cx site here:
https://www.3cx.com/voip-gateways/patton-smartnode-sn4112-fxs/
Provisioned connecting the Patton to the SBC



The patton 4112 is showing in our admin panel and will register a 3cx extension

Inbound DID set to ring extension connected to one port1 on Patton
Second DID set to fax on port2 on the Patton

When we dial the DID phone line does not ring on the patton but does ring from the external number
When we dial the internal extension for the analog port we get an internal server error along with a busy signal

Cannot call outbound from either port

Connected a buttset to the patton and there is no dial tone. Green lights for both ports 1 and 2 are not illuminated.

ext 101 analog extension on the patton is showing as registered under phone
ext 880 is showing registered as a fax fxs/ata under system extensions

We are running latest updates on both the Patton and 3cx hosted platform

Any help would be greatly appreciated.

Attached config file from Patton and the log file from a telnet session while calling both extensions on the Patton.

Thank you!

John

So, 3CX shows the extensions as registered yet you get no dialtone on the Patton (and line lights are not lit), correct?
Have you looked for any errors in the 3CX Activity Log? What does the log show (where is 3CX attempting to end an Invite), when you dial the external DID number?

Correct no dialtone or green lights indicating extensions are active

Looked at the activity logs in 3cx and am getting errors when incoming call is active:

These three errors are showing:

CM503003]: Call(C:163): Call to <sip:[email protected].0.2:5060> has failed; Cause: 503 Service Unavailable/INVITE from 127.0.0.1:5080

When we call the voice extension assigned to the other port on the patton we get:

[CM503003]: Call(C:170): Call to <sip:[email protected]:0> has failed; Cause: 503 Service Unavailable/INVITE from 127.0.0.1:5080

Communication between the SBC and the hosted 3cx causing issues?
