[OpenSIPS-Users] SDP missing in ACK indialog reinvite only in 1.11.5

Mon Mar 21 14:31:27 CET 2016

Hi Louis,

There was a similar discussion back in August [1], concluding with a fix 
[2], made between the 1.11.5 and 1.11.6 releases. Updating to the latest 
OpenSIPS 1.11 will most likely solve this problem.
