Account Polling
The system can use different call type (
Cloud platform
/
H.323 account
/
SIP account
/
H.323 IP
Call
/
SIP IP Call
) to dial a number when more than one account is registered.
The priority of call types is as follows:

If you dial an account, the priority is:
Cloud platform>H.323 account>SIP account
.

If you dial an IP address, the priority is:
H.323 IP Call
>
SIP IP Call
.
If account polling is disabled, the system will select the call type with the highest priority to
place a call by default. In this situation, once the dialed number differs from the call type you are
using, the call will fail. You can enable the account polling feature, the system can try each call
type in order when dialing a number.
You can configure account polling feature via web user interface only.
