Abstract
A computer device may include logic configured to receive a first Session Initiation Protocol (SIP) message from a telephone device; select a first back-to-back user agent (B2BUA) and a first screened telephone number (STN) associated with the first B2BUA; generate a second SIP message that includes a first destination address of the first B2BUA, and the first STN; and send the second SIP message to the first B2BUA. The logic may further determine that an acknowledgement response has not been received from the first B2BUA; select a second B2BUA, and a second STN associated with the second destination B2BUA, in response to determining that the acknowledgement response has not been received; generate a third SIP message that includes a second destination address of the second B2BUA, and the second STN; and send the third SIP message to the second B2BUA.
