I provide support for a client that uses Cytracom for their internal phones and support queues. I also have my own company and use Cytracom for my own phones. On my D2 phone I can easily configure two different accounts, make and receive calls without needing to have two D2 phones. Once I leave the office and need to stay connected by mobile app I'm required to either choose an company to be logged into, carry two cell phones or set up forwarding/find me on one of the two accounts.
Please, let's have the mobile app support multiple accounts or extensions from different companies.
