Fax over IP with Samsung and Cisco


Project of the day is to devise a way to get faxes across a WAN. My telephony 'server' is to be a Samsung OS7400. We've found that we can get a Cisco ATA186 to register as a SIP device to it fairly easily, but the ATA doesn't do fax relay of any sort. We plan to upgrade routers at a potential customer's sites to voice capable routers, and equip them with FXS VWICs. We'll build either H.323 or SIP trunks from the Samsung to the voice gateway local to the Samsung, and then build dial-peers in the routers to route these fax calls accordingly. The remote sites are going to use Samsung IP phones and our goal is to not have any local POTS line at any of the remote sites. Not sure what they'll do about 911 calls yet, but I guess we'll deal with that after we prove this will work.
Since we only have one trunk license in the Samsung we have to get calls into it via T1 connected to our Cisco Callmanager. We use the Samsung for training right now, but we can't dump the SIP trunk and not replace it with something. We're working on that now. Don't know why that is so hard this time around. More to come....

New Job, New Challenge

     I'll be starting a new job on Monday morning, and the first project I'm going to attempt is to get a Comdial DXP phone system to use Microsoft Lync as it's voicemail. Lync is in place already, and I understand there's an Audiocodes SIP gateway device of some sort that I hope I can use to integrate the phone system into Lync. My first concern is whether there's an available interface card on the DXP to connect to the SIP gateway.      I'll go to the site Monday and get an inventory of the phone system, find out what model of SIP gateway they have, and see if I can come up with a plan to make this work. Alternatively, I could find a more common option for voicemail to use on the Comdial, but it is very old, and I don't think it would be wise to invest any money in the system.
