[SR-Users] Issue with UAC restore_mode when restore_dlg is enabled

[jenus at cyberchaos.nl]

And the _uac_to and _uac_fu seem to contain the correct data. But in the 
_uac_tonew i see the <null> value.



                         _uac_tonew: sip:+<null>@voip-dev.domain.nl
                 }
                 {
                         _uac_funew: sip:KPNtest1 at voip-dev.domain.nl
                 }
                 {
