REDUCING VOIP CALL DISRUPTION

Abstract:

In an approach to reducing VoIP call disruption, a current SDP is received from a first party. Whether the current SDP is an initial SDP is determined. Responsive to determining that the current SDP is not the initial SDP, whether the current SDP has a same origin as a previous SDP is determined. Responsive to determining that the current SDP has the same origin, whether the current SDP has a same media attribute as the previous SDP is determined. Responsive to determining that the current SDP has the same media attribute, whether the current SDP has a same order of one or more (a) line media attributes as the previous SDP is determined. Responsive to determining that the current SDP has the same order of one or more (a) line media attributes, the current SDP is prevented from being sent to a second party as a new offer.
