SPA to Voxalot REDIRects?

What this problem boils down to is that a SPA3102 Gateway sends INVITES with From headers equal to the PSTN caller's CID, instead of its VoIP account. When it's redirected by the destination SIP proxy (such as a SPA942 with Cfwd), it tries to authenticate with this CID. Here is the essential SIP code:

Calling:123456@192.168.1.32:5062
INVITE sip:123456@192.168.1.32:5062
Via: SIP/2.0/UDP 192.168.1.31:5061
From: MOBILE <sip:0410000123@au.voxalot.com>
To: <sip:123456@192.168.1.32:5062>
Remote-Party-ID: MOBILE sip:0410000123@au.voxalot.com>;screen=yes;party=ca lling
Contact: Peer1 <sip:0410000123@192.168.1.31:5061>

The Cfwd/REDIR works if there's no incoming CID, or when [PSTN Line]PSTN CID For VoIP CID = No. Effectively this blocks PSTN CID beyond the PSTN gateway, which isn't desireable.

How can PSTN CID and REDIR work together? Is Linksys violating SIP by setting From=PSTN CID, or is Voxalot wrong to authenticate on the From field (presumably not)? How does a Gateway-PBX configuration manage PSTN CID?

I thought of prefixing the CID with a code like 999, but that just throws Voxalot completely.

Is that your mission statement?

It's a fact Tslam, i've provided you with all the information I can see from the logs.

For a free service I can safely say we have provided you with more support than you would otherwise get from many paid services.

Yep I thought you'd say that - you reached a similar conclusion in the recent "Voxalot not working with PBXes" thread.

Anyhow, I don't happen to think Voxalot a really a free service. It's something which you are developing into a commercial franchise; the next Google perhaps. The only thing that's really free is the time we users give you in (unsolicited) development and beta testing.

Tslam we do understand your frustration, however it is very difficult to diagnose this sort of problem without having full visibility of the client side setup.

Part of the premium launch will include a support framework that will enable us to provide personalized levels of support.

Right now, our resources are spread thin working on new features and the aforementioned support infrastructure.

We hope you understand.

In my opinion this could be a mistake. A global mistake. Think about it.
