1. A secure call indicator method, comprising:
- receiving, by a microprocessor, a Session Initiation Protocol (“
SIP”
) message, wherein the SIP message corresponds to a communication session between at least a first communication device associated with a first user and second communication device associated with a second user;
applying, by the microprocessor, a security check to the received SIP message, wherein the security check is for checking trust of a leg of a communication session, wherein the security check inspects each leg of the communication session to determine that each leg of the communication session has passed the security check, and wherein the communication session has a plurality of legs;
determining, by the microprocessor, based on the security check, a security classification associated with the communication session; and
controlling, by the microprocessor, a secure call indicator on one of the second communication device associated with the second user or the at least one first communication device associated with the first user, wherein the secure call indicator indicates the security classification associated with the communication session, and wherein the security classification indicates to the one of the first or second user whether the communication session is secure or unsecure.

Abstract
The concept of a secure call indicator is introduced. In general, the secure call indicator is capable of inspecting the security of signaling associated with Session Initiation Protocol (SIP) messages and comparing the security with media descriptions of the actual media path of the SIP messages. Furthermore, the secure call indicator may be configured to indicate the security associated with a communication session via a physical or virtual notification system.

14. A computer readable storage device having stored thereon instructions that, when executed by a processor, perform a method comprising:
-
receiving a Session Initiation Protocol (“
SIP”
) message, wherein the SIP message corresponds to a communication session between at least a first communication device associated with a first user and second communication device associated with a second user;applying a security check to the received SIP message, wherein the security check is for checking trust of a leg of a communication session, wherein the security check inspects each leg of the communication session to determine that each leg of the communication session has passed the security check, and wherein the communication session has a plurality of legs; determining, based on the security check, a security classification associated with the communication session; and controlling a secure call indicator on one of the second communication device associated with the second user or the at least one first communication device associated with the first user, wherein the secure call indicator indicates the security classification associated with the communication session, and wherein the security classification indicates to one of the first or second user whether the communication session is secure or unsecure. - View Dependent Claims (15, 16, 17)

18. A system, comprising:
-
a first communication device associated with a first user; a second communication device associated with a second user; and a communication server including a secure call indicator mechanism that receives a Session Initiation Protocol (“
SIP”
) message, wherein the SIP message corresponds to a communication session between at least the first communication device and the second communication device;applies a security check to the received SIP message, wherein the security check is for checking trust of a leg of a communication session, wherein the security check inspects each leg of the communication session to determine that each leg of the communication session has passed the security check, wherein the communication session has a plurality of legs; determines, based on the security check, a security classification associated with the communication session; and controls a secure call indicator on one of the second communication device associated with the second user or the at least one first communication device associated with the first user, wherein the secure call indicator indicates the security classification associated with the communication session, wherein the security classification indicates to at least one of the first or second user whether the communication session is secure or unsecure. - View Dependent Claims (19, 20, 21)
