Hi. Does someone tried this scenario? (or like this) -------------------- | Asterisk with | --------------------- ---------------------- ----------->| H.323 and G.729 |----------| Gatekeeper(GNUGK) |------------| Cisco AS5350/AS5400|--------------- E1/T1 line | Registered in GK | --------------------- ---------------------- E1/T1 -------------------- I know that it should work, but there is a bunch of possible showstopers like codecs interoperability, ..... I just wonna avoid buyng another AS5350 Gateway - is always better to use something opensource
