Call screening service for inbound communications
One example method of operation may include receiving a call message intended for a call recipient, removing one or more portions of call message data included in the call message, identifying one or more of a trunk group and an entry point associated with the received call message, adding one or more of a trunk group identifier (TGRP) and a universally unique identifier (UUID) to the call message to create a modified call message, and forwarding the modified call message to a destination network associated with the call recipient.
1. A method comprising:
receiving a call message intended for a call recipient;
removing call origin information from call message data included in the call message;
identifying origin carrier information associated with the removed call origin information and one or more of a trunk group and an entry point associated with the received call message;
adding one or more of a trunk group identifier (TGRP) and a universally unique identifier (UUID) to the call message to create a modified call message that identifies the origin carrier information; and
forwarding the modified call message to a destination network associated with the call recipient.
2. The method of claim 1 , wherein the call message comprises a SIP INVITE.
3. The method of claim 1 , wherein the adding the one or more of the TGRP and the UUID to create the modified call message comprises adding the UUID to a payload portion of an X-header of the call message.
4. The method of claim 2 , wherein the adding the one or more of the TGRP and the UUID to create the modified call message comprises adding the TGRP to a contact header of the SIP INVITE message.
5. The method of claim 1 , wherein the TGRP further identifies the trunk group where the call message was received.
6. The method of claim 1 , wherein the TGRP further identifies a telephone number, a location identifier and an IP address.
7. The method of claim 1 , comprising
retrieving an operating company number (OCN) parameter based on a telephone number included in the call message; and
determining a carrier network associated with a call message origin based on the OCN and one or more of the TGRP and the UUID.
8. An apparatus comprising:
a receiver configured to receive a call message intended for a call recipient;
a processor configured to
remove call origin information from call message data included in the call message;
identify origin carrier information associated with the removed call origin information and one or more of a trunk group and an entry point associated with the received call message;
add one or more of a trunk group identifier (TGRP) and a universally unique identifier (UUID) to the call message to create a modified call message that identifies the origin carrier information; and
a transmitter configured to forward the modified call message to a destination network associated with the call recipient.
9. The apparatus of claim 8 , wherein the call message comprises a SIP INVITE.
10. The apparatus of claim 8 , wherein one or more of the TGRP and the UUID being added to create the modified call message comprises the processor being configured to add the UUID to a payload portion of an X-header of the call message.
11. The apparatus of claim 10 , wherein the one or more of the TGRP and the UUID being added to create the modified call message comprises the TGRP being added to a contact header of the SIP INVITE message.
12. The apparatus of claim 8 , wherein the TGRP further identifies the trunk group where the call message was received.
13. The apparatus of claim 8 , wherein the TGRP further identifies a telephone number, a location identifier and an IP address.
14. The apparatus of claim 8 , wherein the processor is further configured to retrieve an operating company number (OCN) parameter based on a telephone number included in the call message; and
determine a carrier network associated with a call message origin based on the OCN and one or more of the TGRP and the UUID.
15. A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:
receiving a call message intended for a call recipient;
removing call origin information from call message data included in the call message;
identifying origin carrier information associated with the removed call origin information and one or more of a trunk group and an entry point associated with the received call message;
adding one or more of a trunk group identifier (TGRP) and a universally unique identifier (UUID) to the call message to create a modified call message that identifies the origin carrier information; and
forwarding the modified call message to a destination network associated with the call recipient.
16. The non-transitory computer readable storage medium of claim 15 , wherein the call message comprises a SIP INVITE.
17. The non-transitory computer readable storage medium of claim 15 , wherein the adding the one or more of the TGRP and the UUID to create the modified call message comprises adding the UUID to a payload portion of an X-header of the call message.
18. The non-transitory computer readable storage medium of claim 16 , wherein the adding the one or more of the TGRP and the UUID to create the modified call message comprises adding the TGRP to a contact header of the SIP INVITE message.
19. The non-transitory computer readable storage medium of claim 15 , wherein the TGRP further identifies the trunk group where the call message was received.
20. The non-transitory computer readable storage medium of claim 15 , wherein the TGRP further identifies a telephone number, a location identifier and an IP address.
