Walter Posted April 18, 2011 Report Share Posted April 18, 2011 Hello guys I need some help . I have a new project that will put the snomOne in a cloud environment (Virtual Server) I'll go for the 150 version. All remote phones. Client has many stores, usually 2 m9 Handsets and 1 fax line/ credit card machine ;-) So what is the best Fax ATA device for the snom One? I was thinking Linksys PAP2. ? How big of a virtual server do I need for 150 extensions most will have the 2 handsets registered on the same extension. Fax is what I'm not comfortable about. What are your thoughts?

Vodia PBX Posted April 18, 2011 Report Share Posted April 18, 2011 If you run the PBX in the "cloud" jitter is much higher than on CPE, so the virtualization overhead is probably neglectable. But I would be careful that the server is not too virtual, the service provider must not move the VM around from one phsical host to another all the time as this will create major service interruptions for your users. 150 extensions should be okay. The more important number is how many calls you expect. I think the important point here is that you have the option to add more CPU horsepower if you need it (relocate the server on a different physical device if you run short on resources). And you are right, FAX is something important. Apart from using the PBX and T.38 for FAX, you can also consider using HTTPS for the FAX and bypass the whole FAX problem. PAP2 is an option, but I think you can also take a look at AudioCodes and Mediatrix, especially if you are interested inthe HTTP solution.

mattlandis Posted April 18, 2011 Report Share Posted April 18, 2011 Is there anyway that snom could implement a simple fax via https into snom ONE? This would be incredible. (i am of course not aware of what copyrights, legal this would entail...) Quote Link to comment Share on other sites More sharing options...

mattlandis Posted April 18, 2011 Report Share Posted April 18, 2011 https works perfect and industry experts seem to agree it is the future of fax. No need to go through the pbx. You can get seperate DID's. Tell me how many trunks and we can get you going. Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted April 18, 2011 Report Share Posted April 18, 2011 I did a very quick research and found only AudioCodes supporting this right now. AC is a great company, but it would make me feel a little bit more comfortable to know that other vendors also support this... Depending on how it exactly works, it could be very simple to implement this also in the PBX. Quote Link to comment Share on other sites More sharing options...

How big of a virtual server do I need for 150 extensions most will have the 2 handsets registered on the same extension. Fax is what I'm not comfortable about. What are your thoughts? Do not use the PAP2T - this unit is not good for fax. The SPA2102 adapter is much better - run the latest firmware from Linksys ver 5.2.12 which was just released end of Jan/2011. The new firmware made the T.38 faxing much better. You can have the 2 ports on SPA2102 to handle 1 port for faxing and second port for credit card machine. The reason you need credit card machine on second port is because you have to set special settings on that port to get the visa machine to send data over voip. Https faxing is the best - I think the guys over at Nexsip have this running now. Quote Link to comment Share on other sites More sharing options...

It's not simple and I only know of one company that is doing https - they are the ones that made the https firmware that runs in the AudioCodes ATA's.

Walter Posted April 18, 2011 Author Report Share Posted April 18, 2011 So then I guess it will requiere that my SIP Trunk provider can provide HTTP for fax codecs and I will have to terminate on the AC ATA? Quote Link to comment Share on other sites More sharing options...
mattlandis Posted April 19, 2011 Report Share Posted April 19, 2011 No. just that you'll need a https fax provider too. (doesn't need to be the sip trunk provider) Quote Link to comment Share on other sites More sharing options...
Walter Posted April 19, 2011 Author Report Share Posted April 19, 2011 No. just that you'll need a https fax provider too. (doesn't need to be the sip trunk provider) OH OK, getting the idea now. Do you know who provides HTTPS fax? and the adapters? Quote Link to comment Share on other sites More sharing options...
Walter Posted April 19, 2011 Author Report Share Posted April 19, 2011 How much will you guys run on this server: Core 2 Duo E8400 1x Core2Duo E8400 Dual Core 2 GB 1x 250 GB SATA OS Debian I mean how many extensions and CCS will you guys be willing to run here?

Vodia PBX Posted April 19, 2011 Report Share Posted April 19, 2011 The other thing that should not get forgotten is that T.38 can also be run over TCP (or even TLS). This will also be very reliable. At least the Ricoh in our office does that. Quote Link to comment Share on other sites More sharing options...
hosted Posted April 21, 2011 Report Share Posted April 21, 2011 We have a customer using our https fax service today over a clear wimax modem. works great, no way T38 would survive that. As far as using a virtual host on 150 users.. You would pretty much need a dedicated server to do that so it would be wiser to rent a server instead of a VM. For pricing information on the HTTPS FAX ATA's email me burr@nexsip.com db Quote Link to comment Share on other sites More sharing options...

At least the Ricoh in our office does that. The signaling might be TCP/TLS however the T38 transport will still be UDP, and still subject to the same packet loss issues. db Quote Link to comment Share on other sites More sharing options...

I have seen them go a little higher, but that is our magic number. All of our hosted customers are on dedicated blade servers we do not share resources. our blades go from 10 concurrent calls to 35. our 1.5Ghz blades are 10 concurrent calls our 3.8GHZ blades are 35. db Quote Link to comment Share on other sites More sharing options...

Walter Posted April 22, 2011 Author Report Share Posted April 22, 2011 OK I'm checking nexsip, now that will fix the fax side, what about the Credit Card machines? Any ideas on that? Quote Link to comment Share on other sites More sharing options...

I've been checking the snom ONE and Processor is not used that much. What PBX you guys use? Quote Link to comment Share on other sites More sharing options...

voipguy Posted April 22, 2011 Report Share Posted April 22, 2011 You right, I'm loosing my mind. Sorry. The best option would to have your clients Visa machine connect via internet instead of phone line - this way you don't have to worry about SPA2102 or VoIP settings to make the Visa machine work. All the newer Visa machine terminals have that option. Quote Link to comment Share on other sites More sharing options...
