<div>Dear Osmocom & NextEPC Community,</div>
<div><br>
</div>
Today I've added CS Fallback and released NextEPC v0.5.0
<div><br>
</div>
<div>So, I'd just like to test this part with Osmocom project,
but it seems to be a difficult task. The reason is why I have
little knowledge about 2G/3G. Nevertheless, I will try to do
it</div>
<div><br>
</div>
<div>BTW, I don't know if there is anyone who wants to integrate
this big thing.</div>
<div>Even though I'm not sure if this will help, but let me
introduce the configuration of the NextEPC.</div>

<div>To use SGsAP, change the mme.conf as follows:</div>
