Which parameter in the license limits the number of attendants on the U1900 series unified gateway

During the device restart, enter R when the system prompts you to press R to restore the default password. At the prompt "[.Conform to restore password.](Y/N):>", enter Y. The following information is displayed: Success to restore default password! Success to save default password! Then, you can use the default password to log in to the gateway.

All U1900 series unified gateways support SIP/SS7/PRA/R2/QSIG Trunk. U1910/U1911/U1930/U1960/U1981 also support AT0 Trunk, U1980 doesn't support AT0 Trunk. U1911/U1960/U1981 support BRI Trunk, while U910/U1930/U1980 doesn't support BRI.

The voltage and current parameters on the U1980 are listed as follows: Input voltage (AC): 100?240 V AC Maximum power consumption in full configuration: 400 W Input current (AC): 6 A Maximum output power (AC): 500 W The voltage and current parameters on the U1981 are listed as follows: Input voltage (AC): 100?240 V AC Maximum power consumption in full configuration: 220 W Input current (AC): 4.5 A Maximum output power (AC): 300 W The voltage and current parameters on the U1960 are listed as follows: Input voltage (AC): 100?240 V AC Maximum power consumption in full configuration: 220 W Input current (AC): 3.5 A Maximum output power (AC): 300 W The voltage and current parameters on the U1930 are listed as follows: Input voltage (AC): 100?240 V AC Maximum power consumption in full configuration: 220 W Input current (AC): 3.5 A Maximum output power (AC): 300 W The voltage and current parameters on the U1910 are listed as follows: Input voltage (AC): 100?240 V AC Maximum power consumption in full configuration: 200 W Input current (AC): 3.5 A Maximum output power (AC): 300 W The voltage and current parameters on the U1911 are listed as follows: Input voltage (AC): 100?240 V AC Maximum power consumption in full configuration: 150 W Input current (AC): 3.5 A Maximum output power (AC): 300 W

When loading a license on the U1900 fails, perform the following steps to locate the fault: Step 1 Run the show license command to query the ESN and check whether the ESN is the same as that used for applying the license. Step 2 Check whether the number of users specified in the license is greater than the number of users created. Step 3 Check whether the license version matches the device version.

To apply for a license for the U1900 series unified gateway, do as follows: Send related information including the authorization document, ESN, and software version to license@huawei.com to apply for a permanent license file. You can also apply for a license from Huawei SDP platform. For details, see the eSpace U1900 V200R003 License Application Guide (for the SDP platform) that is obtained from the following hyperlink:
