[Linphone-developers] Error when trying to connect first time

[Kamil Szulc]

Hi, community,

I'm getting an error when trying to call for the first time to the
Asterisk server. Registration works correctly. It's weird because
everything works fine after turning the app off and turning it on
again, then calls are available. Any ideas? Error below.

```
2022-02-26 13:51:15:775 belle-sip-error-udp bind() failed for ::0 port
5060: Address already in use
2022-02-26 13:51:15:775 belle-sip-error-TCP bind() failed for ::0 port
5060: Address already in use
New registration state Progress for user id Optional("sip:1001@address:5060")
New registration state Ok for user id Optional("sip:1001@address:5060")
error: Optional(Error
Domain=com.apple.CallKit.error.requesttransaction Code=7 "(null)")
```

Thanks for any advice you can share with me.
