Hi Herald, Thanks for the quick response! My apologize for the delay - I was close to get it working so wanted to put a mail after. GSM_TAP was the key - Thank you for this help. External CC works well now. There was no way I could figure it out, if I hadn't enabled GSM_TAP. It said "Invalid mandatory information" Just compared mncc with internal and external CC - Debugged a little further and realized 1 of the fields of bearer_cap was missing! mncc-python is good - I read your blog. Made some changes (socket path). Although it does fail with "Invalid mandatory information" - bearer cap missing. I will have to look again at the code. *Just an off topic Question*. Osmo-sim-auth and pysim both same projects right? Reason I asked since, I wrote all SIM API's in osmo-sim-auth and was planning to push upstream and then realized there is a project pysim which has all of that ?
