| Upgrade to 5.1 (SIP)
We've been running 5.0 for about a year now and are looking to upgrade to 5.1.
Our current setup:
1G server at corporate office with fiber to the internet
- roughly 15 phones at corporate office
8 branch offices running on DSL with a hardware VPN to corporate
- 1 to 6 phones at each branch
The VOIP concept is great for our setup and the administration is very easy.
Our only issue has been with quality, which we believe stems from the DSL/VPN connection between the branch phones and the corporate server.
It's my understanding that the 5.1 version is a SIP protocol which will allow us to not force our branch phones through a VPN and should therefore increase quality.
So I guess I have 2 questions:
1) Does anyone have any comments about our setup?
2) Has anyone performed the 5.1 upgrade? If so, will it really improve our quality?
Thanks in advance |
