Switch the Realm (Registration Proxy Server)
ATA can register to three different SIP Proxies at the same time. It can receive any one of different
SIP accounts incoming call, and it can switch to anyone's SIP accounts for making calls through
inputting the switch code.
Realm switch code:
1*: Realm 1
2*: Realm 2
3*: Realm 3
4*: Realm 4
5*: Realm 5
For example, the default is realm 1, input the
the telephone set. It will switch to realm 2, and it can make the SIP calls via realm 2.
