Voip.MS/Obi200 outbound calls stopped working after migration from Fido Internet to Rogers Internet

After I migrated from Fido Internet (CODA Hitron modem) to Rogers Ignite Internet 150 ( Technicolor Gen 3 CGM4981COM modem) Voip.MS/Obi200 outbound calls stopped working.

- Internet, WhatsApp, Google Meet are OK

- Inbound Voip.MS calls are OK

What may be a root cause of this issue?

Which Voip provider are you with? The change in ISP may have triggered security on the your provider's side. I had a similar problem with Voip.ms. You may have to login into your VOIP account to authorize the IP to allow it to make out going calls.

"Which Voip provider are you with?"

I am with Voip.MS.
I changed my Internet provider.

Outbound calls started working today.
I still have no clue about why they were not working yesterday.
