Abstract

Methods and systems for routing voice over internet protocol (VOIP) are described. A service provider may provide a VOIP infrastructure for routing VOIP calls. One or more other service providers may join the VOIP infrastructure. A computing device may identify the service provider servicing the VOIP calls and may further process the calls accordingly.

First claim

We claim:

1 . A method comprising:
identifying, based on a received communication invitation message for a voice over internet protocol (VOIP) call to an endpoint, a first service provider from a plurality of service providers that are each configured to route the call to the endpoint; determining, based on the communication invitation message, a VOIP call type; selecting, based on the determined VOIP call type and from a plurality of routing preferences provided by the identified first service provider, a service provider routing preference for the VOIP call; and routing, based on the selected service provider routing preference, the VOIP call.

2 . The method of claim 1 , wherein the identifying is based on two or more from the following being in the communication invitation message:
an ingress trunk name; a calling party domain name; or an organization header value; and
wherein the plurality of service providers share one or more of the following:
an encoder; or
a decoder.

3 . The method of claim 1 , wherein the communication invitation message comprises a session initiation protocol (SIP) invite and wherein the endpoint comprises a recipient user device.

4 . The method of claim 1 , wherein the identifying the first service provider is based on information indicating a plurality of different service providers for different combinations of values for ingress trunk name, calling party domain name, and organization name.

5 . The method of claim 1 , wherein the identifying the first service provider is based on information indicating a plurality of different service providers for different combinations of values for ingress trunk name, calling party domain name, and organization name, and wherein one of the values is blank for the first service provider.

6 . The method of claim 1 , further comprising storing a table indicating routing preferences corresponding to each service provider of the plurality of service providers, for a plurality of combinations of information in the communication invitation message.

7 . The method of claim 1 , further comprising:
receiving the plurality of routing preferences from the first service provider, wherein the plurality of routing preferences indicates a plurality of routing rules for a plurality of VOIP call types; and storing the plurality of routing preferences, wherein the routing is based on selecting a routing rule, associated with a second service provider that shares a VOIP infrastructure with the first service provider, from the stored plurality of routing preferences.

8 . The method of claim 1 , further comprising receiving, by a second service provider of the plurality of service providers, the communication invitation message for the VOIP call, wherein the identifying, the determining, the selecting, and the routing are each performed by a second service provider of the plurality of service providers using a VOIP infrastructure of the second service provider.

9 . The method of claim 1 , wherein the determined VOIP call type comprises one of the following:
a local VOIP call; a long distance VOIP call; an international VOIP call; a help desk VOIP call; a residential VOIP call; a business class VOIP call; an emergency VOIP call; or a 1-800 VOIP call.

10 . The method of claim 1 , further comprising:
receiving, from each service provider of the plurality of service providers, a plurality of routing preferences for a plurality of different VOIP call types, wherein each routing preference provides instructions for routing VOIP calls from subscribers of each service provider.

11 . The method of claim 1 , wherein the routing comprises blocking the VOIP call.

12 . The method of claim 1 , wherein the plurality of routing preferences provided by the first service provider supersede default routing preferences specified by a second service provider that shares a portion of a VOIP infrastructure with the first service provider.

13 . The method of claim 1 , wherein the service provider routing preference for the VOIP call comprises permitting calls to a first country and blocking calls to a second country.

14 . An apparatus comprising:
one or more processors; and memory storing instructions that, when executed by the one or more processors, configure the apparatus to:
identify, based on information in a received communication invitation message for a voice over internet protocol (VOIP) call to an endpoint, a first service provider from a plurality of service providers that are each configured to route the call to the endpoint;
select, based on a VOIP call type associated with the communication invitation message and from a plurality of routing preferences provided by the identified first service provider, a service provider routing preference for the VOIP call; and
route, based on the selected service provider routing preference, the VOIP call.

15 . The apparatus of claim 14 , wherein the instructions, when executed by the one or more processors, configure the apparatus to identify the first service provider based on two or more from the following being in the communication invitation message:
an ingress trunk name; a calling party domain name; or an organization header value; and
wherein the plurality of service providers share one or more of the following:
an encoder; or
a decoder.

16 . The apparatus of claim 14 , wherein the communication invitation message comprises a session initiation protocol (SIP) invite, and wherein the endpoint comprises a recipient user device.

17 . The apparatus of claim 14 , wherein the instructions, when executed by the one or more processors, configure the apparatus to identify the first service provider based on information indicating a plurality of different service providers for different combinations of values for ingress trunk name, calling party domain name, and organization name.

18 . The apparatus of claim 14 , wherein the instructions, when executed by the one or more processors, configure the apparatus to identify the first service provider based on information indicating a plurality of different service providers for different combinations of values for ingress trunk name, calling party domain name, and organization name, and wherein one of the values is blank for the first service provider.

19 . The apparatus of claim 14 , wherein the instructions, when executed by the one or more processors, configure the apparatus to store a table indicating routing preferences corresponding to each service provider of the plurality of service providers, for a plurality of combinations of information in the communication invitation message.

20 . The apparatus of claim 14 , wherein the instructions, when executed by the one or more processors, configure the apparatus to:
receive the plurality of routing preferences from the first service provider, wherein the plurality of routing preferences indicates a plurality of routing rules for a plurality of VOIP call types; and store the plurality of routing preferences, wherein the routing is based on selecting a routing rule, associated with a second service provider that shares a VOIP infrastructure with the first service provider, from the stored plurality of routing preferences.

21 . A system comprising:
a first apparatus and a second apparatus, wherein the first apparatus comprises:
one or more processors; and
memory storing instructions that, when executed by the one or more proc
