有可能实现从电脑到电话，甚至从电话到电话的免费通话吗？不可能免费使用传统电话

to Telco. VzB asks less than 2c per min on long distance calls,for example,
cheap enough even compared w/ VoIP providers...
Within the enterprice of course more and more people dump Nortel PBX
and jump to Cisco CUCM. (or Avaya....)

发帖数: 1055 | 9 Buy one of those Cisco Unified Communication boxes, it has everything, VoIP,
Wireless, VPN gateway, LAN switching ...For off-net calls, just select any
SIP trunk provider, but you do need to have FXO/ISDN VIC card to connect to
traditional PSTN provider for backup, and possibly a FXS port for fax.
The con side is that Cisco Skinny/SIP phones are expensive, you can buy non-
Cisco SIP phones.
Of course you can go with less expensive solutions, but it is not worthy of
the hassle. |

This does not make much sense to me, so if a softphone needs to make a call
to a phone in next cube, the audio traffic has to traverse all the way to
trunk and then come back again? the same would be true for wired/wireless
softphones to access voice gateways when you, presumably, put voice gateways in voip VRF, correct? the same is true for the connection between your voice mail server and Exchange server?

Since I am doing strict priority queue for VoIP and I am marking on the

this?
I might have to use mls qos vlan-based on interfaces facing customers since I do have service policy applied on L3 SVIs. |

1、ATA- 基本上选Linksys SPA1001或SPA3102。一般到ebay买吧？
2、VoIP provider，弃Gizmo选CallCentric，后者好像可以把现有住宅号码port-in，
这样省得改号码。
