A method and system include routing telephone calls from multiple private networks via public lines and trunks in a public switched telephone network (PSTN) to a host switch, at which the connections would begin to run parallel. The host switch routes the telephone calls via a private trunk group to a private facility, such as an electronic tandem network (ETN) node or an asynchronous transfer mode (ATM) switch. If the private trunk group is full or unavailable, the host switch routes the telephone calls over alternate private or public trunk groups and selected carriers.

Approaches to recover from faults associated with multi-homed clients having transport protocol connections that pass through network address translators are disclosed.

Embodiments support seamless switchover of SCTP connections over NAT devices.

According to various embodiments of the present invention, systems and methods for routing telephone calls from host switch to remote switch in a Voice Over Internet Protocol (“VoIP”) network. A host switch in the VoIP network may be communicably coupled with a plurality of remote switches and with a public switched telephone network (“PSTN”); the host switch may receive a call from PSTN having signaling that includes a called party number field and / or a location routing number field. Based on the called party number field and / or the location routing number field, host switch identifies a target remote switch from among the plurality of remote switches that is associated with the called party number field by, for example, querying a database of associations between location routing numbers and / or telephone numbers and remote switches. Host switch then sends the call to identified target remote switch.

The invention relates to a synchronizing method for host parameters of a triple redundancy control system, belonging to the redundancy control field and adopting a method of point-to-point request-response combining timestamp to carry out the parameter synchronization to two hosts in the system. The synchronizing method is as follows: after initialization, a new power up host judges whether other host is on line at first. If other host does not on line, operating according to parameters directly and outputting; if other host is on line, sending a request packet to the host, and the request packet comprises a timestamp T1 when the packet leaving; and then the online host receives the request packet and fills a time stamp T2 when the packet arriving, the parameters that need to be synchronized is packed, a time stamp T3 when a respond packet leaving is filled in and is sent back to the new power up host; the new power up host receives the respond packet and fills a time stamp T4. According to the four timestamps, the network delay (T4 minus T3) from sending the respond packet by the online host to receiving by the new power up host and a clock excursion theta between two hosts are calculated, and a synchronic parameter is corrected by the value of (T4 minus T3) plus theta. The method of the invention eliminates the affect of clock excursion and network delay to the parameter synchronization, solves the output change when the system host switches and ensures the stability and reliability of the system.
