Have tried to upgrade from 5.1.1 to 5.1.3(a) but have faced the following problem,
a) While downloading the patch, the extension form is .gz and not .sgn but somehow wh have tried using a freeware application to download, we managed got an extension form .sgn
b) After upgraded, we have faced that the c-cups soft phones and the wireless phones unable to make internal calls, phones unable to access voice mail, thus have reverted back
Would like to know what are the applications related to c-cups softphones and the wireless ip phones.
Have verified the matrix table, looks like is ok no incompatible issue.
Anyone face that and anyone have done successfully without any c-cups ip phones and wireless phones issues ?
