SIP ALG frequently creates more issues than it resolves. It's advisable to conduct a network test and ensure that it is disabled on your modem/router.
The Voiply Compatible Router is a highly recommended device for T-Mobile, Verizon, Xfinity, and Starlink customers. It's designed to resolve all network-related issues associated with NAT traversal and SIP ALG. This router creates a direct, encrypted connection from your home to Voiply's servers. Even better, it's compatible with your existing router/modem. The company guarantees its effectiveness, offering a money-back promise if it doesn't work as expected.
