My dream one is IAX+SIP(GV)+PSTN gateway. Actually, the IAX100T from China a few years ago is one step from the dream one. However, the company declines the development...
角色C-hing, you might lead a team to develop a branch of switchfin to integrate GV into IP0x. Then I have to say Nerd Vittles might change his mind The kind of job should be done by Atcom
IAX connection is great for its simplicity. My IP01 has been set up in UK now. It turns out that it needs some configurations in the router settings for SIP.
The box is still using snv 432. No serious problem so far. No one way audio. Only difficulty encountered is to dial out via PSTN to a mobile phone number. Don't know why it can't connect and go to consumer service. To other landline and mobile number are ok so far.
I use IAX to connect and after understanding the problem of having a draytek router with several sip devices in the network, I can use sip connection.
Looking forward to integrate others into the system.
