What Proxy/Gateway does Nokia use for testing

Hi,

Just wondering - does anyone on this list know what Proxy/Gateway does Nokia use for developing/testing the SIP stack on the e-series.

I've got a cisco gateway, which seems to work the best with the E-series. Wondering what proxy server they use internally?

Thanks,
Sean

Nokia tries to use various proxies/gateways in testing, not any particular.

Do you have a list of what ones?? Kind of a wishy-washy answer
