Hello and good day,

 I have found some knowledge on amazon that causes me some concern and know very little about as I do not use VOIP yet still wish to be secure as possible within my network.

 I came across this review for a TP-Link router/modem (see screenshot below)

 If I never use VOIP would it be worthwhile for myself to disable this feature on my router for the peace of mind of extra security or am I giving potential threats (i.e "hackers" or criminals) more to work with if disabled? Will disabling the SIP ALG cause any undesired affects to the rest of my home network stability and internet connection?

 Thank you for taking your time, to work this out and help if you feel the desire to respond.
