On the phones, the pabx picks up but is not responding to any keypresses. Tried from iPhone X and 7. Just need an activation to be done on your end since I can't reach the shop.vumatel.co.za any longer :( Vuma has escalted this to their techs...
PBCool having some trouble getting a hold of you guys.
Trying to activate a new installation, VUMA canceled the previous tenant's this morning. Phone menu just loops (not responding to iPhone key presses) and emails not tended to yet :(
