Disabling SIP/ALG on my new Tmobile Home Internet - FAST5688W

The only way around this is to buy a Modem/Router that supports the sim card from the homewifi network of t-mobile. There are a few out there but they cost about 600.00. There's also youtube videos on how to use this. But quite frankly at that point since your line costs you 35.00 a month anyways for a new phone line. You might as well just buy a 299.99 router modem that will work with T-mobiles bandwidths , then you don't have SIP/ALG service and although you are limited to 100mbps about. You can still use your VOIP phone which is necessary now for a majority of remote working.  Eventually T-mobile will get a clue and change their device firmware settings to update their devices to turn off the SIP ALG firewall settings that are embedded in the coding. But until then. They will be losing customers non-stop due to the growing number one use of home internet, VOIP for business. Kinda a moronic thing for them to do , to block SIP on the Appllication Layer Gateway in their firewall when its needed to make outbound calls. Ports 5060 and 5061 are basically blocked which are the calling ports for these systems used by companies globally.  Friend had their t-mobile homewifi for business version and it was the same thing so he returned it within 4 days.
