[Serusers] SMC router configuration

[Joao Pereira]

Hello to all
I have SER working with a public IP, and accepting connections from the internet.
But in a remote office, behind ADSL with a SMC Router (SMC7904WBRA), my NATed clients can register to SER, but cant make calls.
In the router configuration theres a place to configure special applications and has fields for:

trigger port:
protocol: [UDP\TCP]

outside port:
protocol: [UDP\TCP]

I already tried to put the 5060 port and UDP, but the NATed phones just ring, but no RTP passes...
Do someone knows the correct ports to put here?
Thanks
Joao Pereira
