[cisco-voip] Big analog gateway?

[Lelio Fulgenzi]

VG224s are still the cheapest $/port solution out there. 

If you have CallManager anyways, then you can simply tie them into that configuration. If you don't want to do that, you can go H323 for all ports and you don't need a call control mechanism I believe. Although it will be quite a few dial peers. 

If you need PSTN access, then a small 2901 should do the trick. It can act as the gatekeeper as well I believe.

Both audiocodes and quintum make fairly inexpensive devices to do larger scale analog to IP conversion. On the cisco front, you can get pretty good FXS density with the EVM-HD module in an ISR/ISR G2 - should be 24 ports per EVM-HD module and you can put two into a 3845 as an example. May not be the cheapest way to get ~50 analog ports however.

OK folks, in my hospitals, I have about 50 emergency phones, one for each department. We are still primarily Avaya (I'm working on that), but I have a CUCM 8 cluster to service my fleet of 7925 wifi phones. When you upgrade the Avaya, you have about 15 minutes of downtime while it reboots (yes, really and yes, this is current software). 

The emergency phones are used for these planned outages and as a backup for unplanned outages. Right now all of them are 1FBs from the telco (seemed like a good idea 15 years ago!). Needless to say, this is dough we could be saving! 

How do I service 50 analog phones in a relatively inexpensive way? Why is the vg248 gone when I need it? Anyone have a decent large scale analog sip gateway? 

Or, do I convert them all to like 6901 or 6911s? That ends up in the $150-200 range for the set and the DLU - plus a switch port if it's the 6901. 

Thoughts? 

Thanks!
