ADSL Router supports media hairpin

[weihu]

Hi,

I have multiple voip devices behind the same ADSL router. They all register to a remote Asterisk server.

At this stage, to enable them to talk with each other, I have to:

- disable the reinvite feature on the server
- or use Cisco device which supports media hairpin feature

Does anyone know whether there are any low end router which supports the media hairpin feature? I tested my linksys wireles router and a low end netcomm router. Both of them don't support this feature.

Thanks,

Wei
