Hi Tatjana,
I just tried to reproduce the error you're getting from that endpoint and was not able to do so. Can you please open a case with CARE , this way you can share more specific data leading up to the error which will help in the debugging process.
Best Regards,

Subject: API GET Phone Number for BYO SMS returns HTTP 500
Hi,
We are in process of integrationg with BYO SMS. So far, all looks god, but ran into the issue with the API GET Genesys Cloud Developer Center.
When I'm using compliance for the query parameter GET /api/v2/routing/sms/phonenumbers/{PhoneNumebrId}?expand=compliance I'm getting the response 500

Can you please check this?
Thanks,
#PlatformAPI
