ABSTRACT:
An apparatus and a method for enhancing telephony trunk routing includes a call requirements assessor which identifies call requirements associated with a call request. In particular, the call requirements assessor recognizes call requests which are indicative of speaker-phone calls and conference calls. A comparison processor responds to call data received from the call requirements assessor bad comparing the call requirements of a particular call with the quality of service capabilities of an Internet telephony trunk and a non-Internet telephony trunk. A call request which includes a request for a speaker-phone call or a conference call triggers the comparison processor to instruct a call router to route a call via the non-Internet telephony trunk. If a request to activate a conference-call feature or a speaker-phone feature is received from a telephone after an Internet telephony trunk connection has been established, a notification is transmitted to the telephone indicating that the Internet telephony call is incompatible with the activation request. In a preferred embodiment, the request for a conference call is rejected if it is made during an Internet telephony call. In an alternative embodiment, an in-session switch is performed from the Internet telephony trunk to a non-Internet telephony trunk connection in response to an attempted activation of the conference-call feature or the speaker-phone feature during an Internet telephony trunk connection.
