SIP account can't receive incoming calls with TLS activated

When TLS is enabled in the SIP account, no incoming calls are received.

Environment:

• OS: Android 11
• Jami version: Taranis - 20220615-01 (F-Droid)
• Device: Teracube 2e
• SIP provider: voip.ms

Steps to reproduce:

1. Create a SIP account following this post
2. Follow the Jami wiki on voip.ms for the basic configuration
3. Activate: Encrypt media streams (SRTP)
4. Activate: Enable SDES as key exchange protocol
5. Activate: Use TLS Transport
6. Permutate between 5061 (voip.ms TLS port) and the default value for whatever port options available

Expected and actual behaviors:

• On Jami, the account is online
• Echo test work (voip.ms: 4443)
• On the portal, it is registered with secure transport

Expected behavior:

• I can receive incoming calls

Actual behavior:

• I can't receive incoming calls

Following steps:

7. Deactivate "Use TLS transport"

Actual behaviors:

• On Jami, the account is online
• Echo test work (voip.ms: 4443)
• On the portal, it is registered but no with secure transport
• I can receive incoming calls

Following steps:

8. Install Linphone for Android
9. Follow the Linphone for Android tutorial specific for voip.ms here

Expected and actual behaviors:

• On Linphone, the account is online
• Echo test work (voip.ms: 4443)
• On the portal, it is registered with secure transport
• I can receive incoming calls

For the same environment:

• same network
• same voip.ms portal configuration
• same device

it works for Linphone but not for Jami.
