[asterisk-gui] Problem with asterisk gui and multiple accounts from the same provider

[Systemchef]

I tried to configure 3 accounts from the same sip provider (i.e.
sipgate.de, sipgate.co.uk, sipgate.at). I have 3 accounts to register
with the provider. Incomming calls are alle signaled to the last
registered account. The problem ist that the gui generates 3 different
Peers for each of the accounts. If i try to fix this in users.conf to go
all to the same context in extensions, the gui then recognices the first
account as an external sip account, the second and third account als
internal sip users (shown in the Users section)
