Add A PBX
Once Direct Routing is established the next step is to add 1 or more PBXes that will be linked to Microsoft Teams users. You must set up at least 1 PBX. A PBX type is the manufacturer of the PBX. A PBX Location is a single instance of that PBX.
To add a PBX Location login to the SimpleVoIP Connector Portal. If logged in at the Reseller level, navigate to a specific Enterprise and choose the "PBX" option from the sidebar.
Click "Add PBX" in the upper right-hand corner.
The PBX type will be selectable from a drop-down comprised of PBXes made available to the Enterprise when it was created in SimpleVoIP connector by the reseller.
PBX Location: the name of the PBX location. You can use a generic name if you have only one PBX. For multiple PBXes it is best to use a descriptive PBX location name.
PBX Outbound Transport Type: UDP, TCP, or UDP/TCP. We recommend using TCP.
The UDP/TCP option allows SIP traffic to use UDP when possible, but use TCP when necessary due to packet size. We will attempt to use UDP for SIP signaling when we are initiating a flow and the initial INVITE is less than 1300 bytes. In some call situations, this limit is exceeded and UDP traffic would likely fragment and lead to failed calls. In these cases, we will attempt to use TCP. Note: If you are using Host lookup, your PBX must support both UDP and TCP on the same endpoint and port. If you are using SRV lookup then you must have both _udp and _tcp DNS records configured correctly.
PBX DNS Lookup type: Select SRV.
PBX SIP Domain: In User setup, all SIP Users will be created with this domain (Reach out to assigned SimpleVoIP engineer for assistance)
PBX SIP Domain Proxy: If you are utilizing a Session Border Controller or a SIP Proxy in front of your PBX, input the address here. Otherwise, the value will be the same as the PBX SIP Domain. (SimpleVoIP engineer can assist)
Voicemail Feature Code: This controls the feature code sent to the PBX to invoke check voicemail. There is a default for each PBX in SimpleVoIP that can be adjusted to the actual Feature Code used by a specific PBX. (*72)
PBX SIP Domain Proxy Port: Most PBXs use a standard port - 5060. If your PBX uses a different port, change the input to the correct Port.
Codecs: Click each codec you wish to enable, in the order you wish them to be attempted. There must be at least one codec enabled or the system will revert to a default of G.711 A-law.
SAVE SETTINGS. After all settings have been configured.
After saving PBX settings a Success Completed card will appear in the right-hand corner.
Optional PBX Settings
The PBX tab will list the PBX(es) you have created for the enterprise.
To the right of each PBX Location there is an Action Menu that provides you the following options:
Edit allows you to change the PBX Settings as shown in "Add PBX" above.
If you have a Single Sign On portal that you would like your users to be able to access click Manage SSO Settings to manage deeper integration with your PBX. These settings pertain specifically to Teams Application integration. Currently, you can set up a PBX or 3rd party embedded single sign-on end-user portal in the Teams Application with these configurations.
Manage/Add/Bulk Add Feature Codes takes you to the Feature Code pages. Add Feature Codes will provide a guide to set up, management and capabilities of feature codes.
Once you have added 1 or more PBX(es) with the sub-settings you need, please move on to adding users.
PBX Common PBX Troubleshooting Steps
I added Users and they still have a red indicator in the PBX Registration
The PBX info is incorrect or you need to white list SimpleVoIP IP address. Please confirm that the PBX is seeing the attempted registration and reporting on the failure.
Triple check PBX SIP credentials for the user you are installing.
|Conference calls are being managed by Microsoft instead of the PBX
|This is the default Teams setting.
|Switch the settings in Teams Admin to Don’t Allow Dialouts
|I selected the wrong PBX type and now I can’t change it.
|Bad move. PBX details are coded as part of the Direct Route you have built into Microsoft.
|You will need to reset the Direct Routing which requires a Microsoft Enterprise login working with an Admin login. Contact your System Admin. After Direct Routing has been reset, open a ticket with us so we can manually change the PBX type.
|An indicator is red and I need to turn it green
|Many indicators; many causes.
|Here is the full guide for all indicators throughout the portals.
|Calls are failing, either for the whole enterprise or a particular user
|There are multiple possible root causes, some related to PBX Settings.
