[Bug]: Inbound calls rejected with 488 Not acceptable here

[ginkel]

Context

Hi there,

I just set up Linphone 5.2.5 on my Google Pixel 8 (Android 15), but am having difficulties getting inbound calls signaled. Instead, calls are rejected as "488 Not acceptable here". PBX is running FreeSWITCH. Apologies if this just a setting that needs to be tweaked. I have tried various call settings (especially crypto and codecs) to no avail so far.

Thanks,
Thilo

General information

• Device: Google Pixel 8
• OS: Android 15
• Version of the App: 5.2.5
• Version of the SDK: 5.3.47

Expected behaviour

I wanted to receive an inbound call (originating from the regular phone network) on my Android phone. However, the phone doesn't signal any call, which is rejected with "488 Not acceptable here".

To Reproduce

1. Configure Linphone using out FS instance
2. Receive an incoming call
3. Watch it getting rejected

Additional context
