    I like it. An external server means a license anyway, + server, + extra space, power and maintenance costs. Does it have its own SSD storage? -- A(PS|CI)S-SMEC IT consultant Canada / Quebec City area

    What are IT Geeks doin in the telcom business

    IP telephony doesn't make copper POTS and TDM systems totally irrelevant yet (or in the near future), but this will happen at some point with the help of cable companies, FTTH, wireless providers etc. My guess is that it will take decades for POTS subscriber lines to go below a significant...

    Embedded or VM Pro.

    From what I have read on the subject the issues with IPOs and SD cards looked like filesystem bugs, you would probably have experienced them with hard drives as well. I have read elsewhere that there is a VMPro expansion module in the works? Totally a good idea, too bad it's not there yet. --...

    Embedded or VM Pro.

    The problem is, embedded voicemail tops at 6 ports, you can't increase above that. And it's really not enough in the first place if autoattendants are to be used during business hours. I also believe that music / message on hold remove 1 embedded voicemail port when used, even when it comes...

    VoIP SCN Backup

    Which is "depending on higher level protocols to time out". For every call. Works, but a router that can monitor link quality would work better and even use the other route if the link goes down in the middle of a call. Probably without even losing the call (there will be a blank for the time...

    What are IT Geeks doin in the telcom business

    Congratulations Sir you got post #100 :-) Heh. I had to fix things after one of those did a wireless "site survey", called his "tech" guy on the phone, described him what he saw on the field, and ended up: - recommanding only three wireless bridges units for two point-to-point links (one of...

    How does it know that the route is available again then? -- A(PS|CI)S-SMEC IT consultant Canada / Quebec City area

    Embedded or VM Pro.

    Me too. And I also had hard drives that failed faster that the USB sticks did, and so far I don't (yet) have failed SD cards in my collection. That's to the point I now use USB sticks that are actually SD card readers. For multiple reasons USB sticks (especially cheapo ones) can't be trusted...

    What are IT Geeks doin in the telcom business

    It's not the network that is susceptible to the hack/virus/crashes people notice, it's computers. A correctly designed and operated data network remains up 24/7 for years without disruptions, has a reliability that is comparable to TDM systems, and allows more fail-over options than TDM setups...

    VoIP SCN Backup

    The problem with static routing done on the IPO is that "can't talk via the first route" actually means "the interface that would be used to send packets to the router is down". Your ethernet interface will stay up even if the router on the same lan segment stops responding, and your packets...

    Embedded or VM Pro.

    I am pretty certain that that they are in terms of hardware (though not as good as actual industrial SSD devices). Apparently the SD card problems people experienced were caused by software bugs, not actual hardware failing. If backups are a concern I think that's what the second SD card slot...

    Embedded or VM Pro.

    Totally agree with the PRI recommandation. With 12 channels it should break even or cost less, and is totally worth it. The main problem with the embedded VM is that it only has 6 channels (if you pay for the 4 extra channels). You have 12 lines, and over 30 active users. Which means that...

    What are IT Geeks doin in the telcom business

    Even I (of the "IT geek" pack) install TDM IPO boxes and BIX stuff on plywood in basements (and routers, media gateways, ethernet switches, UPS...). Actually I totally dislike stuff that is not wall-mountable, especially stuff that is neither wall-mountable nor rack-mountable. Shelves are evil...

    DSP echo cancellation

    It's more like some analog trunks don't work well with echo cancelers. Even though there are international standards specifying acceptable levels of return on the line (and acceptable performance of echo cancelers), it's not one of the things your telephone company will check and fix as it is...

    VoIP SCN Backup

    Agreed. Your (failover) routing should be done by your routers, not the IPO. Your routers would have two routes to the same remote network, one with a lower priority (= higher "metric") than the other. When the higher priority one is known to be unreachable by the router (and this could be the...

    What are IT Geeks doin in the telcom business

    1 guy for 3000 phones, that's probably a ten-to-1 ration compared to IT folks. Not where I would look for savings. Mission-critical data centers can't work without their computers either, so the correct way to proceed there is first to up the reliability of the data network to enough nines...

    SIP caller's name question

    Can they try not to send "Anonymous" in their Contact: (that is, m:) field? Just m: <sip:....> The way the From: (f:) field is written is a bit strange too (I would expect to see sip:number@provider instead of sip:number@yourIPO there). -- A(PS|CI)S-SMEC IT consultant Canada / Quebec City area

    What are IT Geeks doin in the telcom business

    It's definitely not a matter of less people. In the places I know there is next to nobody having "the phones" in charge, it's almost always completely outsourced even in large shops (these shops outsource IT hardware maintenance and help desk support as well). But there is a matter of cost and...

    What are IT Geeks doin in the telcom business

    Not sure I would trust this guy for a copier either :) At home I have a totally obsolete IBM PII-300 desktop built maybe 13 years ago with a hard drive just a bit younger. Does IP PBX, print server, router, it still manages weeks of uptime (no UPS) and I don't remember ever seeing it crashing...

    Cannont call out on Mega Path PRI

    @Greybeard191 Thanks a lot for the tip because I totally need that for my setup of the week, and felt bad about not setting the switch type to NI2 as it should be. GTD5. Yuck. -- A(PS|CI)S-SMEC IT consultant Canada / Quebec City area
