SIP & NAT

[bobcheese]

Hi All, I am planning a SIP link from 3300 to 3rd party PBX over an MPLS network. Due to the way the customers network is set up we are required to use a 1:1 NAT in the route to the far end PBX.

My question is, will this mess with the voice stream or will a 1:1 relationship be ok?

This should not work as Mitel is telling all that NAT from 3300 is not supported and not possible. Through MBG or vMBG should work.

Ok, well we will see we are past the point of pulling out now. I will report back.

Thanks for the post DoubleUT
