Salesforce - Sangoma Support and SS7 Signaling

Open Source Asterisk is able to support SS7 signaling with our telephony cards using additional software libraries, however Sangoma Tech Support is only able to provide installation assistance under an Open Source Subscription. Bugs , unexpected behaviors or other issues will only be supported by Asterisk Community.
