Optimized Replacement of Calls Using A Grid Parameter
Tools and techniques for optimized replacement of calls using a grid parameter are described herein. The tools may provide machine-readable storage media containing machine-readable instructions for receiving indications of incoming calls, and for populating fields in a contact header structure that are associated with the incoming call. The fields may include a field for containing a globally unique identifier (GUID) associated with the incoming call. The tools may also receive requests to replace a call within a plurality of active calls that are handled by a server. In response to such requests, the tools may search for the call using the GUID.
1 . At least one machine-readable storage medium comprising machine-readable instructions that, when executed by the machine, cause the machine to perform a method comprising:
receiving at least one indication of at least one incoming call; and
populating at least a field in a contact header associated with the incoming call, wherein the field is for containing a globally unique identifier (GUID) associated with the incoming call.
2 . The machine-readable storage medium of claim 1 , further comprising instructions for instantiating the contact header.
3 . The machine-readable storage medium of claim 1 , further comprising instructions for instantiating the contact header, wherein the contact header includes a call identifier field, an originator field indicating an originator of the call, and a recipient field indicating a recipient of the call.
4 . The machine-readable storage medium of claim 3 , further comprising instructions for populating the call identifier field, the originator field, or the recipient field.
5 . The machine-readable storage medium of claim 1 , further comprising instructions for receiving the GUID.
6 . The machine-readable storage medium of claim 1 , further comprising instructions for generating the GUID.
7 . A server comprising at least the machine-readable storage medium of claim 1 .
8 . At least one machine-readable storage medium comprising machine-readable instructions that, when executed by the machine, cause the machine to perform a method comprising:
receiving at least one request to replace at least one call within a plurality of active calls handled by a server; and
searching for the call using a globally unique identifier (GUID).
9 . The machine-readable storage medium of claim 8 , further comprising instructions for identifying the GUID.
10 . The machine-readable storage medium of claim 8 , wherein the instructions for searching for the call include instructions for searching for a contact header structure that includes the GUID.
11 . The machine-readable storage medium of claim 8 , further comprising instructions for replacing the call, wherein the call is associated with the GUID.
12 . The machine-readable storage medium of claim 11 , wherein the instructions for replacing the call include instructions that are compliant with the Session Initiation Protocol (SIP).
13 . The machine-readable storage medium of claim 8 , wherein the instructions for receiving the request include instructions that are compliant with the Session Initiation Protocol (SIP).
14 . The machine-readable storage medium of claim 8 , wherein the instructions for searching for the call include instructions for performing a single query to locate the call, using the GUID.
15 . The machine-readable storage medium of claim 8 , wherein the instructions for searching for the call include instructions for querying to locate the call, using the GUID as a search key.
16 . A server comprising at least the machine-readable storage medium of claim 8 .
17 . The machine-readable storage medium of claim 8 , further comprising instructions for receiving at least one indication of at least one incoming call.
18 . The machine-readable storage medium of claim 17 , further comprising instructions for populating at least a field in a contact header associated with the incoming call, wherein the field is for containing the GUID associated with the incoming call.
19 . The machine-readable storage medium of claim 18 , further comprising instructions for instantiating the contact header.
20 . The machine-readable storage medium of claim 18 , further comprising instructions for instantiating the contact header, wherein the contact header includes a call identifier field, an originator field indicating an originator of the call, and a recipient field indicating a recipient of the call.
