<p>Hello,</p>
<p>is there like a developer mode for this app that allows to
register on a local LTE network? Or you tested with a simcard
built for you own network?</p>
<p>Cheers,<br>
Daniel<br>

<div dir="ltr">Hi Daniel,<br>
<div><br>
</div>
<div>Thank you very much for your information.<br>
</div>
<div><br>
</div>
<div>I have tried AGEphone (VoIP) before.<br>
</div>
<div><br>
</div>
<div>However, I don't have any information on whether
Open5GS (LTE / EPC) + Kamailio's VoLTE can be used
with a normal phone app on comercial smartphones.<br>
</div>
<div>Maybe it's just because I'm not familiar with
this area.<br>
</div>
<div><br>
</div>
<div>So, I asked if there is a general VoLTE
compatible softphone.<br>
</div>
<div><br>
</div>
<div>Thank you very much again.</div>
<div><br>
</div>
<div>Regards,<br>

<p>Hello,</p>
<p>not acting much in this space, but I heard
about something like imsdroid -- probably you
can try to search on the net and see what you
can find.</p>
<p>Cheers,<br>

<p>Hi all,</p>
<p>I have one question.</p>
<p>What softphones can I use when trying VoLTE
(not VoIP) with Kamailio? I would like to
verify VoLTE of private LTE with Open5GS and
Kamailio.</p>
<p>I'm sorry to ask you a question without

VoLTE.</p>
<p>Thank you very much in advance.</p>
