Need help with Vialer

[showenemytime]

Hello.
We are developing a video calling app using PJSIP and Vialer.
We use the latest available versions of libraries that have not changed for a long time.
https://github.com/VoIPGRID/Vialer-pjsip-iOS,
https://github.com/VoIPGRID/VialerSIPLib

Environment:
Xcode: checked the versions 10, 11, 12
Mac OS 10.15.6 and newer

In the last 2 months, we have had difficulties with the remake build Vialer-pjsip-iOS.
The vialerbuild script seems works fine, but we see the warnings in the process of migration
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: warning for architecture: armv7 same member name (audiodev.o) in output file used for input files: ./pjsip/temp/armv7/libpjmedia-audiodev-armv7-apple-darwin_ios.a(audiodev.o) and:
and the file size is half as much as it was before and build does not work in Xcode.

Xcode shows error
Undefined symbols for architecture arm64:
  "_pjsua_vid_dev_set_setting", referenced from:

Did you have this kind of problem? Will you check it, please?

P.S.
For convenience, we put test projects and libraries (unchanged) together
