Point to point call on Sipura 3k with NAT enabled?

[saad]

I am trying to make point to point call from Sipura's 3k Line1. The other sipura has static IP but mine doesnt. When I call I can see them connected and the call even goes through but there is no voice. I am using Linksys 54GS Router to connect Sipura at my location. Will port forwarding on Linksys router help or is their any option to be enabled in Sipura?

I would bet on NAT problems at the receiving end. My recommendation is to register the devices at both ends with FWD numbers and use FWD to call from one device to the other.
