Hi Folks, I have not yet purchased an RUT955 and before I do I wanted to make sure that this product does not implement SIP-ALG. I want to use the RUT955 as broadband link for my office which has 3CX PBX. The PBX does not operate behind router with SIP-ALG enabled in it. Can anyone confirm that there is no SIP-ALG in this product? TIA.
