Rightfax, a Captaris product that centralizes Desktop Faxing and Electronic Document Delivery. I purchased Rightfax to help my company integrating Fax solutions, and save on maintenance and labor costs associated with manual faxing.
I purchased Rightfax with a digital PRI Brooktrout board (specifically a TR1034+E4H+T1+1N). Now, this board also supports T.38. So, why did I choose to use the digital PRI? Well, up till now, I haven’t had alot of luck using the T.38 protocol (probably due to my ignorance), and my users are starting to get very frustrated. So, for the time being, I chose to use PRI.
It took some soft massaging on both the Brooktrout, as well as on the Serial interface on my Cisco 3845, but I have it working. I will start with an overview of my design, before the implementation.
Here is the corresponding configuration on my Cisco 3845:
controller T1 0/0/0
clock source internal
pri-group timeslots 1-4,24
! Config Snipped
no ip address
isdn switch-type primary-dms100
isdn protocol-emulate network
isdn incoming-voice voice
no cdp enable
! Config snipped
dial-peer voice 6799 pots
Okay, so here is some specifics:
CONTROLLER T1 0/0/0
- clock source internal – I am receiving my clock source from one of my T1’s from the Telco side. This command passes the clock source internally on the backplane, for this controller
- pri-group timeslots 1-4,24 – I only have 4 channels licensed on the PRI card for RightFax. Thus, I only want to allocate those channels. Channel 24 is required for the D-channel.
INTERFACE SERIAL 0/0/0:23
- isdn switch-type primary-dms100 – This will change based on your configuration. I am only using it, since I’m using it on my other PRI’s from the telco. Whatever you choose, you must make sure it’s matched on the Brooktrout card.
- isdn protocol-emulate network – THIS IS INCREDIBLY IMPORTANT!! Rightfax expects to be talking to the telco, not another device.
DIAL-PEER VOICE 6799 POTS
- destination-pattern 6799 – This will change based on your dialplan. I chose to use a specific number for testing. Generally, you will create a pattern for your fax numbers.
- no digit-strip – If you will be using DID numbers (you probably are), then you’ll need to send the number along to RightFax. In order to do that, we need to send the digits on, so RightFax can use them to sort out the correct Fax mailbox.
- port 0/0/0:23 – This just directs the call to the Serial interface for Rightfax.
That’s really it. I kept the default configuration on the Brooktrout card, except for the ISDN config (Protocol Options under the Port A tab). For the ISDN config, I just chose what I’ve configured here (i.e. B8ZS, DMS-100 switch, etc). Oh, and you need to modify the max. DID digits. By default, it is set to ‘0’, so I assumed that meant no limit. No, that means 0 digits. Change it. 🙂
