IP PBX Connector

IP PBX Connector

Note

IP PBX replaces the Linked Office feature.

The IP PBX Connector enables integration between a third-party IP PBX system (e.g. 3CX, Asterisk) and myCloudPBX. This is useful in situations such as:

  • Acquiring a new business and temporarily integrating phone systems
  • Migrating from an existing IP PBX to myCloudPBX
  • Custom call routing or hybrid environments

Connector Configuration

On the left-hand side of the screen, you can configure the connector details:

FieldDescription
Connector TypeCurrently only IP PBX is supported.
NameA name to identify this connector (e.g. "Demo", "Sydney Office PBX").
CountryUsed for formatting numbers and dialling rules.
TimezoneDetermines the local time context for logs and call flow operations.
Default Outbound NumberThe number used for outbound calls when none is specified explicitly by the calling extension.
SIP HostThe SIP host address that your third-party PBX will connect to.
Authentication IDA unique ID assigned by the system, used as a username to authenticate the trunk connection.
PasswordThe associated password for authentication.

Note: The Authentication ID and Password are generated when a new connector is created. Use these credentials to configure a SIP trunk on your third-party PBX pointing to the SIP Host.

User Mapping

On the right-hand side of the screen, define the list of Users (Extensions) that will be accessible from your third-party PBX:

FieldDescription
ExtensionInternal extension number (e.g. 880, 881).
Label / NameAn optional name/label for clarity (e.g. "Reception", "Support").
ActionAllows you to delete an existing user from the list.

Adding a User

To add a user:

  1. Enter an extension number in the Extension field (e.g. 891)
  2. Click Add User
  3. Optionally, enter a label for the extension
  4. Click Save Users

These users can then be referenced in call flows, ring groups, and call queues within myCloudPBX.

Example: 3CX Configuration

To connect 3CX to myCloudPBX, configure a SIP Trunk.

Steps

  1. Log in to the 3CX Admin Console
  2. Go to SIP Trunks → Click Add SIP Trunk
  3. Choose:
  4. Country: Generic
  5. Provider: Generic SIP Trunk
  6. Main Trunk Number: your allocated number (e.g. 0285070701)
  7. Click OK

Trunk Settings

DID/DDIsAdd your main number (e.g. 0285070701)
  1. Configure Outbound Rules to use the new trunk.
  2. Map Inbound Rules to ring groups, auto attendants, or extensions as required.

Example: Asterisk Configuration

To connect Asterisk to myCloudPBX, add a SIP trunk in pjsip.conf (or sip.conf if using chan_sip).

pjsip.conf

[mycloudpbx]
type=endpoint
transport=transport-udp
context=from-external
disallow=all
allow=ulaw
outbound_auth=mycloudpbx
aors=mycloudpbx
from_domain=demo.mycloudpbx.com.au

[mycloudpbx]
type=aor
contact=sip:demo.mycloudpbx.com.au

[mycloudpbx]
type=auth
auth_type=userpass
username=123456
password=your_password_here

extensions.conf

[outbound-mycloudpbx]
exten => _0X.,1,Dial(PJSIP/${EXTEN}@mycloudpbx)

[from-external]
exten => 880,1,Dial(SIP/1001) ; Example route to local SIP user

Replace 785217 and your_password_here with the values provided in your connector settings.

Firewall and NAT Notes

*Ensure your firewall allows SIP (UDP 5060) and RTP (typically UDP ports 10000–20000).

*If your PBX is behind NAT, enable NAT traversal settings

*Always test both inbound and outbound calls for audio flow and call completion.
