A process is provided which facilitates providing information to a user in an Internet telephony environment. A Session Initiation Protocol (SIP) message including a SIP message header is received from a user. A string pattern matching operation identifies a stored regular expression pattern which matches a character string in a user part of the SIP message header. One portion of the character string identifies an application mapped to the stored pattern. A further portion of the character string identifies one or more variables for use by the application. The application identifies information by applying the value of the one or more variables and communicates this to the user. The application may be on an Interactive Voice Response (IVR) system.

Session initiation protocol message processing

A method and system for managing channels in a voice response system is provided. The method comprises periodically monitoring utilization of a system resource and determining a number, N, of voice channels required to be quiesced based on the utilization level of the system resource. This number is compared with the number of channels currently quiescing, Q, and the number of quiescing channels is adjusted accordingly. A quiescing channel is disabled when it becomes inactive.

Method and system for channel management in a voice response system

A method of supporting Voice over Internet Protocol (VOIP) media codecs on a voice processing system stores voice response segments in each of a plurality network native formats. Each of the network native formats corresponds to a media codec. The method receives a call from a caller over an IP network. The method determines a negotiated codec for the call. If the call requires a required voice response segment, the method retrieves the required voice segment in the network native format corresponding to the negotiated codec. The method then sends the required voice segment in the network native format corresponding to the negotiated codec to the caller over IP network. If the call includes a voice message from the caller, the method stores the voice message from the caller in the network native format corresponding to the negotiated codec. If the call requires retrieval of a voice mail message for the caller, the method retrieves the voice mail message. If the voice mail message is in the network native format corresponding to the negotiated codec, the method sends the voice mail message in the network native format corresponding to the negotiated codec to the caller over the IP network. If the voice mail message is not in the network native format corresponding to the negotiated codec, the method converts the voice mail message into the network native format corresponding to the negotiated codec, and sends the converted voice mail message in the network native format corresponding to the negotiated codec to the caller over the IP network.
