    FOOD FOR THOUGHT DNS traffic

    If you have a big enough network to require SIP phones and a PBX, you would benefit by having a local caching DNS server on the same network. That won't solve your problem, but it will make DNS requests that much quicker. Going to google dns or your ISP's DNS all the time eats bandwidth and...

    TIPS Remote Users and dynamic IPs

    VPN works very well for wired devices whether it be a plethora of SIP phones or a remote and trunked PBX. All I do is provide my customer with a VPN-capable appliance type router configured to backhaul to my VPN service, and then plug their phones into that router, maybe through a switch if...

    NEED MORE INFO Configuring the OBI 200 as an extension

    You're welcome. There was a blog by "michigan telephone" that covered every aspect of the obi's thoroughly, but it seems to have disappeared like most useful things on the internet. I tried to find it for you by using waybackmachine.org unsuccessfully. Maybe you'll have better luck than me...

    NEED MORE INFO Configuring the OBI 200 as an extension

    Obi Digimap: http://www.obihai.com/docs/OBi-DigitMapCallRoute-Tutorial-v1-1.pdf Digimaps for Obi devices work the same way, with some units having more ports than others. I had a pair of 202's configured as SIP trunks rather than extensions for google voice and as an extension to leverage...

    TIPS Degraded Software RAID

    You're using devicemapper (dm-raid). Here's a writeup on it: https://www.kernel.org/doc/ols/2005/ols2005v1-pages-297-304.pdf Manpage: http://linux.die.net/man/8/dmraid When you're using clonezilla, you can hit the tab key to add parameters to whichever menu option you want to select, and add...

    SOLVED Dahdi Issues - Solved

    This was an aggravating problem because I was trying to solve it in the wrong place. When the system lost power, somehow permissions were messed up when it booted. I solved it with: "amportal chmod" at the command prompt and reboot.

    SOLVED Dahdi Issues - Solved

    I hate to beg for help but Dahdi has always given me a problem. Last night the utility company cut our power "by accident", intending to cut power to my neighbor who was behind on his bill. They "fixed" this 5 hours later but in the meantime the UPS's ran dry and for some reason, my PBX install...

    FYI Is PIAF Good for Big Deployments?

    > how large of an environment is everyone deploying PIAF in? we have around 300 phones I host VoIP for small business and one of my servers has about 425 endpoints. > In a multi box solution / hot standby, to switch from A to B can be almost transparent. Absolutely. My main-office PIAF install...

    SOLVED GV: direct or OBI

    OMG never mind. The problem with GV/motif was my not setting this correctly: https://www.google.com/settings/security/lesssecureapps Funny how the simplest things are the most aggravating sometimes :)

    SOLVED GV: direct or OBI

    I wasn't sure if this belongs in "trunks", "providers" or here. I hope I chose well. I have a large PIAF installation, consisting of three Dell 2650 2U servers, dual 32-bit processers, raid-5, 16GB ram, one in each of three locations, 10-20 SIP extensions per server/location. They are...

    SOLVED Invisible Dahdi?

    Installed PIAF Yellow yesterday, and I'm struggling with the DAHDI configuration. According to this page: http://wiki.freepbx.org/display/F2/DAHDI+%28Analog%29+Channel+DIDs, Dahdi type items should be a selectable menu option in freepbx off the "Connectivity" drop down menu, and none of them...

    FOOD FOR THOUGHT Vitelity Issues

    Hykos as the right idea. Then you can have two VoIP trunks from different providers, using which ever one you prefer until it goes boom, then switch on the fly to the other one. And as a worst case, if your business is small, you can forward that main number to a cell phone or even your house.

    SUGGESTIONS PIAF Backup Alternatives

    If your only concern is PIAF then something like "incredible-backup" is a great tool, however we use a different method because PIAF is one of about 45 servers and whatever methodology we use for one, we need to use for all of them, to simplify restore procedures for the technicians. Our backup...

    TDM400P (2) + Purple + Dahdi

    First, I want to thank all of you for assisting - your time/energy is valuable and I wanted to thank and acknowledge that. To come full circle on this thread, I wasn't able to get dahdi working at all. So... I took a chance at a "monkey solution" and wiped off PIAF and reloaded trixbox, which...

    GVoice In Flames No More

    While I'm a fairly new user here, I have to say Michigan Telephone's writeup about the obi100/110 "appliances" are outstanding. Following his guide (er, blog as he calls it) I got my two GV numbers up and running in about 15 minutes each.
