Unity Express and Unity IP Fax Wizard

[ruben]

We have a Cisco 2811 Router with CME and are going to install an Unity Express module in it.

Will Unity IP Fax Wizard work with that?

Ruben

[Markus Schneider]

No. Unity Express has no ability for fax. It is purely voicemail-only.

Ok. I have searched some more and then my solution will be Cisco ATA 186 2-Port, a regular modem in a PC/Server and Symantec Winfax.

I will then configure CME to passthrough fax/modem to the Cisco ATA. I think that will work...

[Markus Schneider]

Be aware of the following issue: CSCed47764. You have to configure the ATA as an H323 device (with an H323 image) and then configure for G711 and disable VAD. On the CME you must have an inbound dial-peer that has fax rate disable and modem passthrough.

After going from SCCP firmware to H323 firmware the ATA does not registrer itselt to CME anymore... do I have to set up ephone and ephone-dn for the ATA to work or is dial-peer enough? If I have to set up ephone can I just do this manually and don't care about that the ATA don't registrer?

The ATA has now ata001192f85b7b firmware

Version: v3.1.2 atah323 (Build 040927A)

I'm in Norway, so here we use a-law codec.

Here is config for ATA:

AudioMode: 0x00140014

ConnectMode: 0x90001400

RxCodec: 1

TxCodec: 1

LBRCodec: 1

Here is config for CME:

voice-port 0/0/0

compand-type a-law

voice-port 0/0/1

And of course... currently it does not work since I'm writing this...

Something more I have to do/change?

An H323 device won't register with CME. It is all done through the dial-peers. On your dial-peer 30, the destination-pattern should be the number you assign to the fax machine. The incoming called-number should be that same number (it needs to match the calling number in the setup message that gets sent from the ATA when it places a call). I'm not extremely familiar with the ATA configuration, but it would need to have some configuration in it (the equivalent of the dial-peers in CME), so that any time you dial 0T (or whatever you want to call) it points to the CME's IP address.
