Hi Daniel,

I am not using any developer mode for the phone app. I have tested using a test network with programmable SIM cards from Sysmocom and COTS UE. In order for the Android phones to perform an IMS attach I make use of Carrier Privileges to force enable the VoLTE feature. More instructions can be found in the following link https://github.com/herlesupreeth/CoIMS_Wiki. From my experience if you are using a test network (PLMN 00101) you have maximum success in activation of VoLTE on the phone.

On the iPhones, the IMS is by default enabled for all PLMNs

Best Regards,
Supreeth

Hello,

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?

Cheers,
Daniel

Hi Shigeru,

Having written Open5GS (LTE / EPC) + Kamailio's VoLTE tutorial myself here is my 2 cents on VoLTE client. You can use any Android phone / iphone with its default phone app to test VoLTE (try to avoid Samsung phone as much as possible)

Best regards,

Hi Daniel,

Thank you very much for your information.

I have tried AGEphone (VoIP) before.

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.
Maybe it's just because I'm not familiar with this area.

So, I asked if there is a general VoLTE compatible softphone.

Thank you very much again.

Regards,

Hello,

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.

Cheers,
Daniel

Hi all,

I have one question.

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.

I'm sorry to ask you a question without much understanding of Kamailio, VoIP and VoLTE.

Thank you very much in advance.

Best regards,

--Shigeru
