I'm curious re. your statement about P-CSCF. What does LI and transcoding
have to do with Kamailio? As already mentioned these functions are
available only in B2BUA which Kamailio is *not*. What other issues then did
you have with P-CSCF impl. using Kamailio. Also, how did P-CSCF even get
into this thread?
<sarcasm>BTW, you forgot to mention the awesome price of Acme in your
comparison to other alternatives</sarcasm> ;)

Hi Melanie,
Now I'm curious about which tests are you mentioning. Also, Acme
Packet/Oracle as many different SBCs models, which can be selected
according with the customer's requirements.
When talking about the infinite number of features I wasn't really
thinking in H.323. Although, probably there were customers like you a
couple of years ago that thought they wouldn't need some features and
regret they didn't pick Acme Packet, after they received new requirements
on their networks. Acme SBC can also route using any SIP message element.
Just use an HMR and according with what you want, just add a Route header
(as simple as that... :) ).
Regarding traffic shaping, you can also do it based on media-profiles.
Comparing traffic shaping with Acme Packet DoS protection doesn't make much
sense. Their DoS is one of the features that made their SBC what it is now,
the leader worldwide. And do you know what it means? It is tested against
any tool out there performing attacks (more customers means more testing).
Can you say the same about the ABC demo?
One additional thing is that you can for sure say that when deploying a
Acme Packet SBC you won't have issues interoperate with other vendors. This
is not marketing material, again this is based on the number of
customers/deployments that exists worldwide.
Not to mention real HA (out-of-the-box), simple configuration (yeah, I've
already implemented an P-CSCF using Kamailio and it was a mess...),
transcoding, LI, etc.
Hope it helps,
Luis

Don't understand how is it possible to
compare Kamailio with the Acme
Packet SBC. Just to give an example, the DoS mechanism available on the AP
SBC can't be
compared with any other solution available on the market. You will also
have HMRs, SIP Routing options out-of-the-box (like time of the day
routing, sip
method based, cost based, traffic classification based, lb, trunk group,
enum,lrt, multistage, route header based, redirect, etc etc) and infinite
number of
features that you will for sure miss if you plan on making that
replacement.
Hi Luis,
the acme product seems actually underperforming compared to Wladimir's
SBC demo and measured by the technical capabilities I am interested in.
What continues to confuse me is the apparent mixture of technical and
marketing terms. The infinite number is respectably long but it includes
many features I will not need like H.323 or appear to be marketing. For
example it appears that ABC demo can route by any SIP message element,
which is clearly superior and necessary, especially in a deployment with
proprietary header fields. Even if it does not make such a long
element-by-element feature list :). Similarly it includes several types of
traffic shaping, which seems little different from the DoS protection
offered by former Acme. Acme's multistage lookup you mentioned seems to be
just a fix to quite imperfect design which didn't anticipate cascaded
routing logic. I mean I am a little bit careful about assessing
technological supremacy based on marketing material.
Is there possibly some truly technical-based comparison? I tried to look
it up in the archive but did not find some.
Melanie
