You may face a situation where some of your vendors do not provide the proper service quality. This causes a high Post Dial Delay which results in discontented customers. To prevent such a negative experience, a "comfort" ringtone can be generated by PortaSwitch as soon as the incoming call is received and while PortaSwitch performs the actual negotiation with the outgoing carriers. For the caller it will appear as if the call is already being connected to the called party. This functionality may be enabled by defining the corresponding value in the Service Policies and can later be assigned at the account level.
