I had a issue with voip on my new TPG modem from 24.12.2021 and after numerous attempts by different support people I had no luck in resolving this issue.Today 5.1.2022 I was fortunate to be transferred to Voip specialist by name of Maria Rina.She was absolutely plesure to have a conversation with, her knowledge and troubleshooting was excellent.Maria Rina thank you for your time and support I am very grateful for all work that you have provided in short time slot. Once more thank you for all and KUDOS to you. John
