A method includes establishing a modem connection, receiving an on-hold request over the modem connection, comparing a cumulative time that the modem connection has been on hold to a threshold value, and resolving the on-hold request based upon the comparison.

Devices, softwares and methods for selectively limiting the total modem-on-hold timeout time of a single log-in session

A network device and a method for its operation are disclosed. The network device has a first interface to a client device to allow reception of client device signals and a second interface to a packet network to allow transmission and reception of modem relay signals. A processor translates between modem relay signals received or transmitted on the second interface and client device signals received or transmitted on the first interface. In one implementation the modem relay originator and the client device are collapsed into one device and the first interface is implemented as a virtual interface.

Modem relay originator

A modem data aggregating gateway that supports modem relay functionality for permitting reliable switching of modem traffic between a VoIP network and a data packet switch Internet Protocol (IP) network, s.a. the Internet. The modem relay aggregator may receive modem data encapsulated as Voice over IP (VoIP) data packets in accordance with a Simple Reliable Protocol Transport (SRPT) mechanism. The packet data may be error corrected and/or decompressed before being repackaged for forwarding to the ultimate destination. In the event that the destination is itself an IP device, the modem relay aggregator may forward the packets directly over the IP network. As a result, if the destination of a modem call is an IP device (such as a Web site or other Internet-enabled device) the technique eliminates two points from a processing path in which digital signal processing (DSPs) would otherwise have to perform modem protocol processing. Otherwise, minimal modem reformatting can be performed at the aggregation point.

Device to terminate a modem relay channel directly to an IP network

A network device is disclosed. The network device has at least one port to receive modem over network signals. A router routes data associated with the modem over network signals received from an aggregator. The aggregator uncompresses the modem over network signals and sends the data associated with the signals to the router directly without relying upon a digital signal processor.

Modem relay aggregator device

Devices, softwares and methods limit the total Modem-On-Hold ('MOH') timeout time of a single log-in session. When a logged in user requests a Modem-On-Hold session, a server counts the cumulative time spent during individual MOH sessions. Once a limit is exceeded, then subsequent MOH requests are denied.
