 |
|
There has been some success using the 3810 series routers with a SIP
image as an up to 6 port gateway.
One fellow has even been able to come out of the 3810 T1 port into a
channel bank and derive up to 30 channels, 24 from the T1 and 6 from the
AVM with daughter boards.
No extensive testing has been done regarding how many simultaneous
channels can be up at one time, but that was not the intended use
This even works with the minimal 3810 equipped with 8 Meg Flash and 32

As you might have seen from a couple of my threads, I have been
looking at Fritz! and Cologne cards, both of which require
development against a specific version of asterisk/zaptel (e.g.
chan_capi), which is intrusdive and causes a lag in deployment.
I was thinking a better approach might be to use a seperate gateway,
such as a Cisco 1751 with VIC-2BRI-NT/TE talking SIP to Asterisk, much
like like an SPA3K in the analogue world.
Any success stories?

I am using a Cisco router as a PRI gateway with SIP. I have no experience with
BRI, but it should work as long as you have DSP cards for voice processing
(the BRI card can do only data calls, and DSPs are needed for voice).

We use PRI, not BRI, with Cisco gateways and it works great. Rock solid.

Working with various Cisco 2821 with PRIs, works perfectly. You
shouldn't have any problem running Cisco routers for this (although I
haven't used BRI for voice, I'm sure it'll work equally well). Just make
sure you have the dsp's necessary installed for the simultaneous calls
on the router you're planning to use.
