What do manufacterers need to enable VOLTE on devices
Not having VOLTE is quiet an annoyance when you have been using it previously on other handsets. what are the specifics regarding enabling volte by both carieer and manufacterer? what information do they need to enable the service?
Manufacturers have to include the proper configuration for VoLTE/VoWifi in their devices, e.g. ISM, Gateways, etc. VoLTE/VoWifi has to be configured a little different than the usual VoIP like e.g. SIP. The GSM Association has a Device Settings Database (where telco's can provide the needed information for handset manufacturers/OEMs), into slides can be found here: www gsma com/futurenetworks/wp-content/uploads/2017/02/Device_Settings_Database.pdf (insert dots after www and before com) Sadly, I guess the database is for registered vendors/telcos only..

Click to expand... Click to collapse is it the responsibility of the MNO to liaison with the phone manufacturer to provide the VOLTE / VOWIFI settings? (or atleast make available) and thus the manufacturer would update the settings via an update? is it possible to get the settings manually via a device that already has volte? what im trying to figure out is this i have two phones. a huawei p20 and a oneplus 6 they both support the same bands so no issues there volte works on my p20 and not my oneplus 6 - this is confusing. my operator clearly favors huawei (as they sell it in store) so they provide the required information (or do they add configuration to the network) to get the volte working my p20 was not purchased via my telco so there is no telco based firmware required to get it working. if possible can we pull the information required from the phone / telco and make available for others to enable VOLTE?
From what I think I read: MNOs: At least the three big players here in Germany whitelisted tested handsets until about beginning of 2017 - then I guess they decided they tested their networks enough and now you can read on their pages that it's (solely?) the OEMs part of work to include the correct config tu support VoLTE/Wifi in their Firmware (e.g. Android release). In principle, the MNOs should send the needed details how to configure for VoLTE/VoWifi to GSMAs database, where the phone manufacturers could access it to implement in their phones - so there's no contact between MNO and phone OEM necessary at all. Of course, if a MNO sells a branded phone, they make sure that phone had that specific MNOs VoLTW/VoWifi settings embeded (and maybe ONLY for that MNO ) . Maybe if we find a Qualcomm Snapdragon 845 based phone we'd be able to copy the configs for other providers. Seems the OP6 currently (5.1.8) has these configs included: OnePlus6:/data/vendor/radio/modem_config/mcfg_sw # cat mbn_sw.txt cat mbn_sw.txt mcfg_sw/generic/apac/airtel/volte/mcfg_sw.mbn mcfg_sw/generic/apac/idea/commerci/mcfg_sw.mbn mcfg_sw/generic/apac/reliance/commerci/mcfg_sw.mbn mcfg_sw/generic/apac/vodafone/volte/india/mcfg_sw.mbn mcfg_sw/generic/china/cmcc/commerci/volte_op/mcfg_sw.mbn mcfg_sw/generic/china/cmcc/lab/conf_vol/mcfg_sw.mbn mcfg_sw/generic/china/cmcc/lab/nsiot_vo/mcfg_sw.mbn mcfg_sw/generic/china/cmcc/lab/tgl_comb/mcfg_sw.mbn mcfg_sw/generic/china/ct/commerci/hvolte_o/mcfg_sw.mbn mcfg_sw/generic/china/ct/lab/cta/mcfg_sw.mbn mcfg_sw/generic/china/ct/lab/volte_co/mcfg_sw.mbn mcfg_sw/generic/china/cu/commerci/volte/mcfg_sw.mbn mcfg_sw/generic/eu/ee/commerci/mcfg_sw.mbn mcfg_sw/generic/eu/elisa/commerci/fi/mcfg_sw.mbn mcfg_sw/generic/eu/h3g/commerci/denmark/mcfg_sw.mbn mcfg_sw/generic/eu/h3g/commerci/uk/mcfg_sw.mbn mcfg_sw/generic/eu/telefoni/commerci/uk/mcfg_sw.mbn mcfg_sw/generic/eu/telia/commerci/norway/mcfg_sw.mbn mcfg_sw/generic/eu/telia/commerci/sweden/mcfg_sw.mbn mcfg_sw/generic/na/att/volte/mcfg_sw.mbn mcfg_sw/generic/na/tmo/commerci/mcfg_sw.mbn mcfg_sw/generic/oem/lab/volte_pt/mcfg_sw.mbn mcfg_sw/generic/oem/lab/volte_te/mcfg_sw.mbn mcfg_sw/generic/oem/oversea/commerci/mtnl_bsn/mcfg_sw.mbn mcfg_sw/generic/oem/oversea/commerci/mcfg_sw.mbn mcfg_sw/generic/sea/chunghwa/commerci/tw/mcfg_sw.mbn mcfg_sw/generic/sea/fareasto/commerci/mcfg_sw.mbn mcfg_sw/generic/sea/tm/commerci/mcfg_sw.mbn mcfg_sw/generic/sea/ytl/commerci/mcfg_sw.mbn Click to expand...

See my last sentence in my last post Those modem configs seem to include seperate config files for selecting the correct bands, etc. I'd guess that mostly the directory entries with "volte" contain VoLTE settings

[REQ] ROM compatibility patch for Telstra Australia.
Hi, Looking for a ROM patch to have better carrier capability with carrier Telstra Australia telco so advanced 4G capabilities can be used on this network. Goals are... - VoLTE Compatibility - VoWifi Enablement - High Speed 4GX services Let me know what you need. I can test on a 5T. Friends can test on a 6.
Unlikely unless Telstra supports it directly (which they don't)… So don't get your hopes up!
