I need to buy 8 BRI port ISDN BRI board but I don’t know which board is better. I have few choices:
- OpenVox B800P (with or without SoftEcho??)
- beroNet BN8S0 Asterisk PCI Card; 8 BRI ports
- Sangoma A500 8 port
- Gerdes PrimuX 8S0 PCI Card
Can you suggest me which is the best or at least the one which you have used and have good expirences.
Does PCI-X or PCI-E card interface has any influence in functioning?
thank you very much
