Abstract
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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
102 words
A method for selectively routing outgoing calls over one of a plurality of outbound lines including a voice-over-data-network line comprising the steps of: evaluating quality of service (QoS) requirements of an outgoing call; selecting an outbound line over which to route said outgoing call from a set of outbound lines which include said voice-over-data-network line if it is determined that said voice-over-data-network line provides a level of QoS which satisfies said QoS requirements; and automatically routing said outgoing call over a non-voice-over-data-network line if it is determined that said voice-over-data-network line does not provide a QoS level which satisfies said QoS requirements.
Claim 2
Independent Claim
102 words
A method for selectively routing outgoing calls over one of a plurality of outbound lines including a voice-over-data-network line comprising the steps of: evaluating quality of service (QoS) requirements of an outgoing call; selecting an outbound line over which to route said outgoing call from a set of outbound lines which include said voice-over-data-network line if it is determined that said voice-over-data-network line provides a level of QoS which satisfies said QoS requirements; and automatically routing said outgoing call over a non-voice-over-data-network line if it is determined that said voice-over-data-network line does not provide a QoS level which satisfies said QoS requirements.
Claim 3
Dependent Claim
57 words
The method of claim 1 wherein said evaluating step includes determining whether said outgoing call is one of a speaker-phone call and a conference call, said routing step including automatically routing said outgoing call over said non-voice-over-data-network line if it is determined that said outgoing call is said one of said speaker-phone call and said conference call.
Claim 4
Dependent Claim
32 words
The method of claim 2 wherein said evaluating step includes monitoring an outgoing call request for a protocol element representative of one of a speaker-phone call request and a conference call request.
Claim 5
Dependent Claim
45 words
The method of claim 1 further comprising the step of providing notification to a communication device from which said outgoing call originated that a selected voice-over-data-network line is incompatible with activation of one of a speaker-phone feature and a conference-call feature in said communication device.
Claim 6
Dependent Claim
39 words
The method of claim 4 further comprising the step of preventing an activation of one of said speaker-phone feature and said conference-call feature in response to an attempted activation of one of said speaker-phone feature and said conference-call feature.
Claim 7
Dependent Claim
23 words
The method of claim 1 wherein said step of evaluating QoS requirements includes determining a class of service associated with said outgoing call.
Claim 8
Dependent Claim
29 words
The method of claim 1 wherein said selecting step is a step of selecting said outbound line from said set of outbound lines which includes an Internet telephony trunk.
Claim 9
Independent Claim
78 words
An apparatus for enhanced telephony trunk routing comprising: means for recognizing minimum requirements associated with a call request; means, responsive to said recognizing means, for comparing said minimum requirements to QoS capabilities of a voice-over-data-network line; and means, in communication with said comparing means, for routing an outbound call over a non-voice-over-data-network line in response to said call request based upon a determination that said QoS capabilities of said voice-over-data-network line are insufficient to satisfy said minimum requirements.
Claim 10
Independent Claim
78 words
An apparatus for enhanced telephony trunk routing comprising: means for recognizing minimum requirements associated with a call request; means, responsive to said recognizing means, for comparing said minimum requirements to QoS capabilities of a voice-over-data-network line; and means, in communication with said comparing means, for routing an outbound call over a non-voice-over-data-network line in response to said call request based upon a determination that said QoS capabilities of said voice-over-data-network line are insufficient to satisfy said minimum requirements.
