i have a UC server of which the version is 5.1.previously the uca client version on iphone is 5.1.34.0 .it worked well that i could make&receive calls when i'm out of my office. Recently i upgrade the client version to the latest, i couldn't use it . it seems like the sip softphone couldn't connect with MBG or 3300,and i tested using another 3rd sip softphone that the MBG works well.
Has anyone see this happen?Thanks.
