Hi,
We are using Cisco5350 as a gateway with 2 E1 cards (part#
AS535-DFC-2CE1) to terminate calls. We need 2 more gateways, my question
is can we save some money and use Asterisk + PCI E1 cards?
I've had the same issue lately. I need to set up a 4E1 / g.729 solution.
Asterisk way
========
- 4 asterisk boxes with 1 E1 card (approx $2k each)
- 120 g.729 licences ($1.2k)
- 1 SER box to dispatch the calls on the 4 asterisk boxes ($1k)
Total: 4 * 2 + 1.2 + 1 = 10.2
In the end, I went on voipsupply.com and saw that they offer Audiocodes
mediant 2000 (4 E1 version) for about $10k. Since this box also does SS7
(which is nice if you want to properly interconnect some day), can scale up
to 16 E1 and is conveniently packed in a 1U rackable unit, I have decided
to go with Audiocodes.
Since I am not set up yet, I can't tell wether it is a good decision or
not. I will let you know :)
Cheers,
Jean-Michel.
Hii Jean-Michel,
Couple of notes, I didn't find Audiocodes at voipsupply.com. As far as the
E1 is concerned, I think that there are many standards for R2-E1 signaling.
Cisco support many variations, not sure if these cards or Asterisk support
such wide variaty of R2 signaling. Check Cisco paper on this
http://www.cisco.com/en/US/products/sw/iosswrel/ps1826/products_feature_guide09186a00800dc5cf.html
Final note, I can get a used Cisco5350 for around $7000 with 2E1 cards, your
solution seems a bit pricey compared to a used Cisco. Any advantages or
features that come with Asterisk that can't be done with a Cisco5350?
Regards,
Linuxman.
