yes, I agree with you. I verify with a sniffer and asterisk manages RTP flows. The problem is asterisk decode and then code again RTP flows. This function requires 5-7% CPU On my test-box (Linux rh 7.3 on P3 600 GHz). This solution don't scale without dedicated HW, I think!
Another problem is codec supported: ok for G.711, G.729. I don't know for GSM BUT: what about video codec? what about proprietary codec or ciphered codec? Do you have any suggestion on how I can manage this with asterisk? I'm very interested into asterisk as sip-to-h323 translator.
