Hi,
I'm interested in inspecting TCAP/MAP interactions between hlr-msc, but it seems osmo-msc osmo-hlr are using a custom protocol(GSUP).
Are there any options to do so?Any suggestion would be appreciated.
I saw some references to RestComm, moji-mobile and signerl(seems abandoned), any of these combinations would work with osmo-msc/hlr?
A side question: is GSUP the only custom protocol used in osmocom gsm network?all other interactions are based on 3GPP?

Best Regards,
amir.
