[cisco-voip] Sip design question

Mon Apr 6 09:59:59 EDT 2015

Just go with the Acme Packet SBC. ;)  It’s the most widely deployed SBC, HA works flawlessly, it’s certified (and used) by all the major carriers and it’s the only non-Cisco SBC certified by Cisco for CUCM/UCCE/CVP etc.. It doesn’t hurt that the web interface has built in ladder diagrams which is way easier than reading debug output, although it obviously has debug as well.

I was making note that CUBE-SP (which if you've ever used, is a substantially different beast than any other flavor of CUBE) is EOL on the ASR 1K (http://www.cisco.com/c/en/us/products/collateral/routers/asr-1000-series-aggregation-services-routers/eos-eol-notice-c51-732167.html).

> My assumption right now is, CUBE on a 4k router running IOS-XE is no different than CUBE on IOS on an ISR G2.  The first link, the CUBE Book, should be used for either platform and is just plain CUBE. Not Enterprise, not SP, just CUBE.
