I have tried the following:
1. set 'internal and loop LCR' in ADM 220.
2. set LCR Type 'Both'. Compared Digits ' 1** ', DMT1 010101 , DMT2 010101 , DMT3 010101 in ADM 221
3. set Networking Number Plan Bin : 1 in ADM 222
CO Group :5 for sip call.
Then tried to dial 110 it shows on the screen no route to destination. And in the trace it shows:
H450_MakeH4501SupplementaryService:512 OSS Err Msg :
Networking Feature Not Installed..
Please, check Lock Key..
How ever the SIP doesn't need any license.
