I'm not sure why you assume a switch to VoIP will help in that regard - in practical terms that means the SIP protocol for the voice (and SMS) signalling. While SIP is going to be the way forward, the specs are really full of ambiguity and not that well though out features. Most commercial vendors of SIP servers include full scripting languages in order for the admins to "normalize" the protocol in order to try to smooth over incompabilities - I can guarantee you that when phones are released in the wild with a SIP stack the telco hasn't tested, things will stop working until they've implemented workarounds for the SIP flavor of the day.
- drzaiusapelord 12y agoSIP is software. What runs on my cellular modem and its stack is firmware written by yet another party. If SIP app #474 is screwing up, I switch to SIP app #475. This all can be done in userland as an application. Changing out my GSM stack? Yeah, I can't do that.
- noselasd 12y agoWell, with VoLTE currently being implemented in networks and phones, that SIP stack used to realize VoLTE on the phone can pretty much be considered firmware too. However, you might fiddle around with various other SIP clients and find one that works for you. The other hundreds of millions of mobile phone users are not going to do that - so the problem will persist.
