Create a SIP Trunk.
Eg For U1911 is 100 per trunk.

Once you saw the Error Message “Exceeded the Maximum Number of SIP Trunk “:

then you can check the total of Trunk & Circuit for your current U1900 Series.

Above shows 6 Trunk with 100 Concurrent Call per Trunk.
1 SIP Trunk ( 100 or less can be configured . if you configure 50 Circuit / concurrent Call per trunk , then you can create 12 SIP Trunk )
As long as Total of circuit do not exceed 600. Sample as below picture:

Total : 600 Circuit we can create for U1911 Version : V200R003C50SPC600.
