SIP 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 #47

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.

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.
