We have Zoiper configured on some window 7 PCs, intermittently they go to registering and fail to connect the only fix we have is to reboot the PC, this is sometimes happening midway through a call.
I have tried different SIP on the machine when it fails but without a reboot it will not connect.
I have reinstalling Zoiper but it keeps returning to registering.
any help would be appreciated.
windows 7 pc fully patched
Zoiper is 2.43v
