I would like to know if the HWIC 4-Port ISDN Card can be used for voice.
Do I have to use the VIC-2BRI-S/T to support voice?
thanks in advance!
Nice to have you back posting solutions here! +5 points for this and for all your great work :)
In this first doc that Juan linked, it has this note;
"The Cisco 1841, 2800, and 3800 Series Integrated Services Routers with the Cisco 4-Port ISDN with S/T interface HWIC provide customers with a choice of converged platforms that offer best-of-class data, security, WAN access, and voice services in a single system. The Cisco 2800 and 3800 Series Integrated Services Routers embed voice functions directly inside the router, enabling customers to deploy voice services by installing digital signal processors (DSPs) and advanced integration modules (AIMs) for IP telephony conferencing, voice gateways, and Cisco UnityÂ® Express voicemail and automated attendant. For call processing, customers can enable the Cisco Communications Manager Express solution as part of Cisco IOS Software and reconfigure the same software to support Cisco Survivable Remote Site Telephony (SRST) for centralized call processing with Cisco Communications Manager. Such an integrated solution enables rapid service deployment, increases efficiency of network operations, and provides opportunities to protect, grow, and optimize your business."
This seems very confusing, as I always thought the same info applied as you nicely suggested. Can you explain what Cisco is referring to here.
It cannot be used for voice.
Only VIC-xxx cards can be used for voice, as the V indicates.
