I think one of important things is the capacity you are looking for.ACME does 
give you better scalability and better troubleshooting capability, but if you 
are only looking for couple hundreds of concurrent calls, you probably can live 
with CUBE to keep your cost lower.

Hi Terry,
 
I do quite a bit of CUBE, and have done a bit of Acme as well.
 
There were some recent partner sessions that talk about some interesting things 
coming for CUBE, so it’s worth making sure you are
 getting latest roadmap info.
 
My main comparison points..
 
# HA
 
In enterprise there was HA on CUBE, and it was improving in each release (but 
there are caveats with it)
Have found Acme HA to be seamless and rock solid.
 
# Deployment
 
Cisco has some great interop guides – if you go with a carrier that has spent 
the money, a lot of the hard work has been done for you
 in terms of testing (as you know SIP can be implemented and configured in many 
different ways – if someone hasn’t done a lot of testing up front, you do 
sometimes end up adding SIP profiles and tweaks as you discover issues)
 
Acme has some very thorough guides – I’m not sure if they have interop testing 
with carriers – given they are in SP’s a lot, there
 is a good chance they do. I’d look into it that with the Acme SE. Talk to 
prospective ITSP’s about their testing, and supported SBC’s.
 
# Ops
 
CUBE enterprise is great, IOS, most people are familiar. You will most likely 
need to train people on Acme
I find troubleshooting a bit of a let down with CUBE. Basically log to buffer, 
copy to file, or packet captures. Wireshark with ladders
 or TranslatorX are great, but it’s getting the files there that bugs me.
Alternatively, there did seem to be a few 3rd party tools out there, but you 
are probably looking at $$$
 
Acme has web interface, list of calls and then ability to drill down with 
ladder diagrams, messaging capture etc. You should see this
 before making decision.
 
Some good knowledge on Acme forums
Acme has very flexible manipulation – CUBE is quite good too (and they have 
great profile testing tool) – plus you can also use CUCM
 LUA on the SIP trunk
 
# On your other notes
 
Centralised – this is great for flexibility DR etc, standard stuff be aware of 
the call volumes over the WAN, caller ID considerations
 for emergency and local pizza shop type services
 
WAN – we terminate on existing equipment, and Acme is in a VLAN, I think this 
is most flexible.. you have a very flexible set up in
 Acme in regard to networking, lots of zones, interface options etc.
 
Transcoding – I think you could still utilise CUCM registered transcoders for 
the ASR scenario..

 
Virtual - We use virtual Acme, it had some teething problems in very first 
versions (and a clunky license on USB stick thing going
 on) but it seems to be good now
                We don’t have transcoding / media resources in the virtual 
edition
 
Flow through / around – a lot of designs the carrier doesn’t have connectivity 
into the rest of the network, so flow through is quite
 typical.
                However, we do have carriers here that have SBC’s on your WAN, 
so flow through can be nice here – it also then makes
 CUBE HA less important, i.e. if call is set up, media is from end point to 
carrier SBC already (if no xcoding involved)
 
So I won’t say one way or the other, just my thoughts on things you can 
consider.
I like both, and will continue to work on both!
 
Cheers,
 
Tim

Subject: [cisco-voip] SBC/SIP Trunk Design queries
 

Hi List,
 
I am working on to finalize the SBC vendor for one of our environments. I have 
a couple of queries related to the SIP Trunk design and SBC vendor 
choices(basically CUBE vs Acme
 Packet). I would really appreciate if anyone with SIP Trunking/SBC expertise  
(Cisco/Acme Packet) can provide some input on the below queries:
 
1)     
CUBE vs Acme Packet: First of all Cisco has marked the CUBE SP Edition product 
line for EoL, exiting the SBC Service Provider segment, so leaving only SBC 
Enterprise as the option. Although at this stage we are looking for an 
enterprise grade
 SBC but it will be a plus if it has the potential to step up into a SP SBC in 
a multi-tenanted environment. I was comparing AP 3820 with the CUBE Ent ASR1k-x:
 
CUBE provides no HA (though in some documents it says, came out from a meeting 
with the Cisco SME informing HA is not available), No transcoding (due to lack 
of DSP on ASR1K), No
 Multi-tenancy support  with all of these features supported in a 3820 SBC 
Any feature better in CUBE that I may have overlooked? I am aware that CUBE 
configuration etc. can be easy compared to Acme Packet but apart from that any 
solid reason to choose
 CUBE over AP?
2)     
HA vs Non-HA: HA is obviously the preferred approach and looks like only 
possible with AP. Can anyone confirm the HA works as claimed by AP? Due to the 
costs involved in double the equipment – whats the common approach followed 
here HA or non-HA?
3)     
Centralised Design: We are planning on a centralised SIP solution (with SBCs at 
both the DCs), anything to be careful of?
4)     
Transcoding: CUBE ASR1K does not support transcoding (due to to lack of DSPs on 
this platform). Normally we would have an agreement with the provider on 
codecs, but still any scenarios when a SBC would need transcoding or on-board 
DSPs ?
5)     
WAN link termination – If we are to provision new WAN links for the this SIP 
service, what’s the preferred approach – terminating WAN links directly on the 
SBC or on the existing routers, does Acme Packet supports WAN link termination?
6)     
Media flow around vs flow thru – Any comments on which approach is better? I am 
preferring flow through at this stage. Any suggestions?
7)     
Acme Packet Virtual SBC: I was looking into AP virtual SBC although it has a 
limited scalability at this stage, but would like to hear any input if anyone 
is using this.
 
Thanks in advance.
 
Terry
