BroadSoft SCA not work behind AudioCodes SBC after Yealink upgrade to V80
The Yealink phones displays "Shared Line Unavailable" after upgrade to V80 when try to seize line.However , it works without problem in V73.
According to SIP message flow , both Request:SUBSCRIBE & Request : NOTIFY has 200 OK reply.
Yealink model :
T46G (28.73.193.45 / 28.80.193.95)
T48G (35.73.193.40 / 35.80.193.95)
T21P_E2 (52.80.193.70 / 52.80.193.95)
Does anyone has any idea about this problem ?
