After the sdk upgrade, sip registration fails and the following error is reported

[wuyinzhi]

I am using the latest linphone-sdk 5.4.0 to integrate into my own project.
There is an app using the old sdk 3.~ on my test phone. After directly updating to the app using the latest sdk, the following error will occur during sip registration and the callback method of registration will not be called:

liblinphone-warning- [LIME] No LIME server URL in account params, trying to fallback on Core's default LIME server URL []

However, when I uninstalled the old version of the app, the sip registration succeeded after reinstallation.

May I ask where the configuration is required to solve this problem? Look forward to your help, thank you!
