Introduction
This document provides instructions on how to configure ProSBC to interoperate with the Restcomm Communications platform as a service (CPaaS) system.
Restcomm CPaaS platform provides programmable voice like IVR service, programmable SMS service, mail, chat services and more, for service provider and enterprise customers.
ProSBC acts as a Session Border Controller to protect the Restcomm CPaaS platform and provides many essential protection features for voice communications over SIP and RTP traffic.
With the example below, a softphone - PhonerLite, and a real mobile phone are used to provide an originating endpoint that will call through ProSBC to Restcomm platform.
Furthermore, in this example, ProSBC AWS is used, but in fact, any ProSBC platform will be able to achieve the same setup.
Network Diagram and Call Scenarios
This section provides the simplified network diagram containing Softphone, Mobile phone, service provider, ProSBC, Restcomm system, and the call flow scenarios.
- Restcomm welcome announcement - PhonerLite sends 'direct call' to ProSBC with called information 1234@52.60.132.155 where 52.60.132.155 is the public Elastic IP used for voip interface in this ProSBC AWS. ProSBC makes a mapping of called number to 1234@netg2.restcomm.com before making an outgoing call to Restcomm platform. PhonerLite hears a welcome greeting from Restcomm platform. Configuration steps (available in different sections of PhonerLite Configuration, ProSBC Configuration below):
- IVR DTMF acknowledgement - PhonerLite sends 'direct call' to ProSBC with called information 1234@52.60.132.155. ProSBC makes a mapping of called number to 1234@netg2.restcomm.com before making outgoing call to Restcomm platform. PhonerLite hears welcome greeting from Restcomm platform with IVR to acknowledge the DTMF tones pressed. Same configuration steps as in call flow 1 with addition of PhonerLite DTMF setting :
- IVR DID full number - PhonerLite sends 'direct call' to ProSBC with called information 1234@52.60.132.155. ProSBC makes a mapping of called number to 13105894010@netg2.restcomm.com before making outgoing call to Restcomm platform. PhonerLite hears welcome greeting from Restcomm platform with IVR to acknowledge the DTMF tones pressed. Same configuration steps as in call flow 1 with addition of PhonerLite DTMF setting :
- Calling DID registered called number with IVR - Mobile phone is calling an international number 902129550330 through Mobile operator and SIP provider. 902129550330 is a registered number in SIP provider. ProSBC registering to this SIP provider (NAP) as a user for this 90212955033 and act as a termination point for this number. Once Mobile phone calling 902129550330, ProSBC detecting this called the number and forward it out, with remapping called number of 13105894010@netg2.restcomm.com to Restcomm platform. This call will also get IVR DTMF acknowledgment for DTMF tones pressed. Same configuration steps as in call flow 3 with addition of ProSBC register to NAP with username and password :
- IVR DID full number outside call - PhonerLite sends 'direct call' to ProSBC with called information 1234@52.60.132.155. ProSBC makes a mapping of called number to 13105894010@netg2.restcomm.com before making an outgoing call to Restcomm platform. PhonerLite hears a welcome greeting from Restcomm platform with IVR to ask the caller to press '1', which will enable a separate call back from Restcomm platform. This separate call back is then routed through ProSBC to the SIP provider and Telecom operator and onto an outside number of a Telecobridges office phone number set. Same configuration steps as in call flow 4.
PhonerLite Configuration
This section provides PhonerLite configurations for the solution.
PhonerLite direct call setting
Below are sections required to setup outbound direct call on PhonerLite,
Server setting: All Proxy/Registrar and Domain/Realm are empty
User setting
Network setting
Codecs and DTMF setting
For dialout, we can specify the called number as 1234@52.60.132.155 where 52.60.132.155 is the public Elastic IP used for voip interface in this ProSBC AWS.
ProSBC Configuration
This section provides ProSBC configurations for the solution.
ProSBC Local NAT Traversal setting
- See NAT section in Toolpack:Tsbc IP Network Settings 3.0
ProSBC NAPs setting
- See Create SIP NAP and Create Open NAP
- Here, SIP NAP will be Restcomm NAP and Service Provider NAP, and Open NAP will be from PhonerLite
ProSBC register to NAP with username and password
- The following sections need to be set, as in example below,
- In this example, ProSBC is behind NAT, so local NAT method is set
ProSBC routes setting
- See Create a Static Route
- Here, we set the SIP end points (NAP) to and from as required in each call flow scenario
ProSBC route called remapping
- The following section needs to be set, and depending what called number remapping required as in each call flow scenario,
