I have recently moved our office over to almost a 100% sip environment.
What we have realized is we still want an ANALOG backup line for two reasons
-
If our internet is down or call quality is really poor due to issues out of our control, we can then use the analog.
-
In the event of a power outage We can quickly move the analog line to a analog phone.
We do very little volume, but this is what I am trying to figure out.
- Should I go with an analog card and just setup a ZAP/dahdi trunk
or - Should I go with a sip ata or gateway and use that?
Prices are pretty similiar…
Any suggestions?
Last, we currently have a fax line, is it a no brainer to never run an analog fax through the pbx? The reason I ask is I was thinking we could save some money if I used the Analog fax line through the pbx, but in those extremely rare scenarios something is down like the internet, I could utilize the fax line for outgoing & incoming calls and just temporary disable the fax.
I’m sure a lot of these questions to a VOIP PRO indicate I don’t know what I am talking about, but there is good reason, I don’t:), please lend your opinions on a good practice of how I should implement PSTN lines for a small office.
