Looking for some advice and where better to ask then here…
Currently we are using a Siemens HiPath 3350 and we want to replace it, so I thought it would be a good time to look at VOIP solutions, but am new to it all (VOIP and Asterisk). I do have experience running linux servers, etc. I would like to know if it is possible (of course it is!) to replace our current setup with Asterisk and what I need to get that accomplished.
Here is our current setup:
Siemens HiPath 3350 with several ISDN lines. About 6 wired phones hooked up, 2 dect stations which are connected to about 6 cordless phones. There is also a analog line going from the HiPath to the faxmachine (which in turn is daisy chained to the fax server. the fax server receives the faxes, fax machine is used to send faxes). I am not sure if the fax line is a seperate analog line or if it is using one of the isdn lines.
What would we need to replace that with a Asterisk setup? I would like to retain 1 ISDN line for use of emergencies, in case the internet connection drops out. Which would serve as a backup line for Asterisk to use? How would faxing work? Can that go through asterisk as well? There are many VOIP providers, but these are hosted providers, if we have our own Asterisk PBX, we no longer need a hosted provider? But we still need some sort of provider for phone numbers and to route calls over internet to normal phone lines?
In the future we would also like to be able to call to our warehouse directly without costs. Would we need another Asterisk server on location or can they just log into the existing server directly?
Any help and insight would be appreciated.
