Good morning everyone,
I have a current setup that is using the Cortelco VoIP 8211 ATA - 821121-ATA-PAK ATA
and it seems like Cortelco isn't making these devices anymore and I would like to find a replacement for it. Would prefer Cisco if there is one or if anyone has any idea please advise.
This important thing is that it has to work the same as the one listed below. Thank you any input would be greatly appreciated.
