Does Adtran channel bank "Total Access 624" support G711 and T.38 protocols? Thank you, Steve
The TA600 Series does not support VoIP SIP. It does support VoIP MGCP. The VoIP MGCP does support G.711. I have not seen any reference to T.38 and MGCP, only T.38 and SIP, so I would say the TA600 does not support T.38. Also, it does not show up in a search of the TA600 manual.
You would need the TA924 to support VoIP SIP and T.38.
