Hello again to Phil and others at WxC,

I hope you all had a great holiday. I am planning to move two of our business lines away from Telecom and over to a pair of VFX lines via a PAP2T or SPA2102. I remember we talked about this last year, but the Linksys data sheets for both devices are identical when it comes to Fax Support:

1) Fax Tone Detection Pass-thru
2) Fax Pass-thru using G711

Both devices appear exactly the same in this regard, yet the VFX "Hardware" page says that the PAP2T is "Not recommended for faxing".

When we discussed Fax Support last year, it was mentioned that some other device supported T38 FoIP whereas the PAP2T doesn't and hence would be a better pick for faxing in future once VFX upgrade their servers, thereby rendering the PAP2T unable to support faxes anymore.

At least, that's how I think the discussion went...

Question: Is the SPA2102 the best device to choose for Fax Support and if so, why?

Secondly, I am planning to use Call Diversion to forward our calls from our Telecom lines to VFX at least in the interim until Number Portability is implemented on April 1.

It would be nice if the outgoing Caller ID in our ATA could be set to match our original Telecom phone number so customers don't get confused by the strange number appearing on their cellphones.

Question: Can I nominate the outgoing Caller ID I wish to be programmed for both lines of our ATA?

If you can answer these questions, I will go ahead and order the necessary hardware.

Thanks Guys.

I think the SPA2102 has T38 (protocol for Fax over IP).

I don't think they can alter the Caller ID as WxC don't have rights to the Telecom numbers - yet, and this would amount to "spoofing". The way I am resolving this issue for my clients is to simply permanently block the out going Caller ID. This works fine as an interim solution until number portability

Hi Grant,

I am away still untill the end of the week but a quick answer to your questions

Question 1
At this stage the devices listed in the linksys range are all the same with the exception of the PAP2 range as they do not support T38 and will probably not according to linksys, so really it will be what you require for your office setup, the SPA2102 is the nearest equivalent to the PAP2 range, but any other device from the linksys range should work exactly the same way for Fax Support.

Question 2
On this one sorry we can not manipulate the ANI as we do not own the original Telecom number and we would not be allowed to , it would be a kind of number spoofing if we presented their number from our network, we would be illegally presenting a Number that was not allocated to us

Regards
Phil Moore

Thanks Coffeebaron, that's a good suggestion. I will do the same for now.

Aha, I just found this in the Data Sheet for SPA2102:

Fax: G.711 Pass Through or Real Time Fax over IP via T.38

Then I had a look through the Technical Manual for the SPA2102 and finally found this statement buried in Appendix E:

Fax Capability T.38 Fax

Earlier I was looking for "T38" instead of "T.38" which was the reason I didn't originally find any mention in the SPA2102 manual.

I have also noticed that the SPA2102 appears to be a later generation of hardware in that it supports 100BaseT (instead of only 10BaseT like the PAP2) and no doubt there are other improvements as well.

For the sake of $33 extra, and on the strength of your recommendation, I have ordered the SPA2102 to get that extra degree of future-proofing.

Once it arrives and the numbers are provisioned, I will setup Call Diversion and trial the 2 VFX lines for a week or two and make sure they are up to the job before requesting disconnection of the two analog lines and setting up Call Redirection for the remaining time until April 1.

At that stage I will have just one remaining analog line (instead of 3) for ADSL and dedicated fax usage, saving me a minimum of $87 per month on line rental and "smartphone" services alone, not to mention the much better per minute call charges on VFX
