Does anybody have any recommendation (or warning notice ;-) ) for analog VoIP gateways with 4 or 8 analog ports (either FXO or FXS) with the following characteristics:
- Support for SIP v.2 (RFC3261)
- Support for T.38 Fax relay over IP
- Stable enough for operations in an unmanned environment (no need for a technician to reset them if some lines get stuck ;-) )
- Inexpensive
First-hand experiences only, please, no hearsay...
Thanks in advance
