I understand that when connected to cloud version of erpnext you can use their mobile app which is available on playstore. Is there a way to access the same on locally installed instance. If yes could explain me to how i can integrate the mobile app please. If not is there anyone willing to take up on that project? I am willing to sponsor the same for the community.
Secondly, can ERPNext connect to the telephony hardware available in the market such as PBX?
