That's sorta of an answer. Is it a completely separate gateway? Is SIP REGISTER the only thing changing? Why is it changing?

Btw, this is a great thing to start working on. I'm looking forward to it.

It is expected to be a gateway with SIP+GSM MAP to the outer world, without changing OpenBTS core; Meanwhile SIP Register seems wiil be replaced.

Are you doing this inside of OpenBTS, or with an external service?

Hi

I'm preparing to implement a legacy GSM roaming for OpenBTS network.

To start with, I'm trying to get a minimal list of mandatory MAP services to allow foreign subscribers to roam inside OpenBTS. CAMEL is not discussed now.

Your help is appreciated.

Regards, Dmitri
