Re: [asterisk-users] Asterisk as an analog call recording solution (was: Recording outbound analog calls with X100P)
John Novack and Time Bandit, Thank you for your excellent advice and for correcting me on the 12V power connector issue. I feel confident to move forward on this project now.

Time Bandit wrote: Is it possible to record outbound analog calls using an X100P? I was asked if I knew how to record all calls for a shop with 4 analog phones transparently to the end users. I thought Asterisk was a good fit for this and I envisioned using either Digium TDM400Ps or Sangoma A200s with 4 FXO and 4 FXS modules. The FXO modules would be connected to the existing PBX and the FXS modules to the existing analog phones. Then with a simple dialplan, all inbound and outbound calls could be recorded by Monitor. I wanted to mock this up using some X100Ps that I had laying around, but found that I could only record inbound calls. I believe that I need an FXS interface to record outbound analog calls but my past experience is with T1 interfaces, so I could be mistaken. Of course you can, if you have 4 FXO and 4 FXS, you could make a really simple dialplan and record the calls that pass through it, incoming or outgoing, and the users wouldn't even know that there is a pbx between them and the PSTN. You will need a lot of space to keep them all, but you could make a simple cron job that would erase any recording older then, say, 2 months. Also, you would have the benefit of having CDR hth Thank you for the confirmation and the warning about disk space. Now I need to decide between the Sangoma A20202 and the Digium TDM2411. I'm leaning heavily toward the Sangoma card for the following reasons: - It doesn't require a 12V power connector for the operation of FXS modules. - It is compatible with 5v and 3.3v PCI buses. - It shares PCI interrupts properly. - It maintains a single synchronous PCI interface for all FXO/FXS ports (additional daughterboards are added to a backplane bus connector) - It has a better form factor. - It is less expensive. These are rather compelling reasons, but I'd still like some feedback from the list prior to making a purchase. Both cards offer hardware echo cancellation for an additional cost. Do the benefits of hardware EC justify the expense in this scenario?

Thank you for the confirmation and the warning about disk space. Now I need to decide between the Sangoma A20202 and the Digium TDM2411. I'm leaning heavily toward the Sangoma card for the following reasons: - It doesn't require a 12V power connector for the operation of FXS modules. Maybe, never used it so I can't confirm, but I doubt it since I'm wondering where it would pull the needed power for the FXS (from the PCI bus ???) - It is compatible with 5v and 3.3v PCI buses. - It shares PCI interrupts properly. - It maintains a single synchronous PCI interface for all FXO/FXS ports (additional daughterboards are added to a backplane bus connector) - It has a better form factor. Depends, if you want to put more than 4 ports in a 1U server, should be easier to put a full-length TDM2400P than try to squeeze 2 A200 cards side-by-side. - It is less expensive. These are rather compelling reasons, but I'd still like some feedback from the list prior to making a purchase. I've seen lots of good comments on the Sangoma cards and on their support. I never used the A200 but I can confirm that Sangoma say they support FAX calls, while Digium say that the TDM2400P was only designed for voice. YMMV Both cards offer hardware echo cancellation for an additional cost. Do the benefits of hardware EC justify the expense in this scenario? Usually when you bridge 2 ZAP channels you don't need echo cancel. I would buy without the echo canceller and if you really have echo that you can't get rid of with software echo can, you could add the hardware echo can after. With Digium's TDM2400P you can add the echo can after. With Sangoma, I think you have to exchange the card for one with it. You should call Sangoma to confirm (http://www.sangoma.com/main/contact) Thank you, You're welcome ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I'm leaning heavily toward the Sangoma card for the following reasons: - It doesn't require a 12V power connector for the operation of FXS modules. It certainly does! - It is compatible with 5v and 3.3v PCI buses. - It shares PCI interrupts properly. - It maintains a single synchronous PCI interface for all FXO/FXS ports (additional daughterboards are added to a backplane bus connector) - It has a better form factor. - It is less expensive. If the need for a connector isn't a killer, the Sangoma A200 is a much better choice. They have a 5 year warranty The will work with any modern motherboard They have good/great support. If it doesn't work, they will NOT tell you to try another motherboard If by chance you need pulse dial, they have a different driver that may or may not be on the website. Ask David in support for that. If you have boards other than the A200, keep in mind that it takes up 24 channels, used or not, so if, lets say, you have an X100 in addition ( don't know why you would ) and its driver is loaded second, it will be channel 25 Sangoma is the wise choice, in my opinion.
