[solved] VolteLab No packet
« on: March 11, 2019, 03:41:38 AM »

My company bought the Volte Lab and after a few tries in Lte enb mode, everything worked fine.
We are now trying to sniff data in GSM nipc mode.
All the setup seems fine, 2 phones are able to communicate (sms and call are working), but no matter on which interface we are listening to with wireshark, there is no packet related to a call or sms.
So we don't know how the labkit and the minicore are communicating, since we don't see any packet getting exchange by them.

Any clue on what's going on ?

I NiPC mode the labkit doesn't communicate with the MiniCore. The NiPC contains a basic implementation of the logic for  MSC/VLR, SMSC and HLR functions locally.
To see any communication between Labkit and Minicore use any of the other modes: roaming, dataroam or LTE ENB.
For the first two modes you can look at the SIP, GTP connection between the Labkit and the Minicore. SIP is for registration, calls and sms and GTP is for data.
In the LTE ENB you should look for S1AP connection.
