Hi guys, I have just bought a Linksys WRT1900ACS for use with Hyperoptic as the router they supply is a POS. Anyway, I note that you have managed to get it working with the CPA112, but does anyone know if it is possible to do so without getting a CPA112? I was thinking Hyperoptic Socket->WRT1900ACS->WRT LAN1 to HyperHub WAN->HyperHub Phone port (FXS) to Phone. I connected this up and it actually worked for about 2 minutes, before the phone became deregistered, presumably due to inaccessibility. A quick google suggests the problem is probably the SIP ALG, and the way it uses ports (5060 static for initialising connection, any random port for RTP, seriously who designs such a [censored] protocol??) Anyway, I was hoping that someone could shed some light as to how one might set it up. I Have forwarded 5060 and 5061 to the Hyperhub WAN, and set port triggering on 50000-65535 which appears to be the default for the HyperHub. Any ideas on how to get this working?
