Hi, I have an RC7611 with R9 FW. As per data sheet VoLTE is supported, but I would like to deactivate/disable it. How do I do it? How to check about this feature?
i don’t think you can disable it
To check this feature, you can dial a voice call by "ATD1234567; " to verify
OK, I have inserted a TRE SIM in one module and tried ATD, but I get response as ‘NOCARRIER’. Does it mean VoLTE is supported, but SIM Card is data-only or something ? I am testing on RC7620 now.

(xxxxxxxxxx is my phone number)
does your SIM card support VOLTE? (you can test with your mobile phone)
did you add semi-colon after the phone number?
I now tried with my personal SIM (instead of the test SIM), which has every support and I got an OK response and also call to my mobile phone… does that confirm VoLTE is supported? I have at!selrat set to LTE ONLY.

OK
I believe VOLTE is supported…
Does the peer side have ring tone?
BTW, why do you need to disable volte feature?
