Honza, obviously you never configured Cisco for SIP, so why did you answer the question? Only to promote your company unneeded products?
Before you give advise, make sure you know what you are talking about.
I have configured many times Cisco with SIP without a SIP Server.
SIP call signaling messages are never initiated by a SIP server, anyone who claims that, should go and read SIP RFC.
If you still have doubts check:
For SIP call flows examples with and without SIP servers.11th November 2005 at 23:42 #30181SIP ServerGuest
>3. Brekeke (not really free, I think the free license is up to 100 units).
Brekeke’s SIP server is completely free to personal/educational use.12th November 2005 at 07:58 #30182Honza VomackaGuest
I am perfectly aware how to configure Cisco gateway to use SIP without a SIP server. However this scenario is something you can use in your lab or for very basic service. But how do you configure things such as least-cost routing then?12th November 2005 at 21:02 #30183To Honza,Guest
It doesn’t look like you know much about voip or sip in particular.
Even your company uses b2bua for LCR not a SIP server, don’t you know that?
Which brings another huge limitation of PortaSIP, no one mentioned before. If I shell 40K to buy your product for LCR, I can not route in h323 (so I loose all of my low costs carriers), and even in SIP I’m quite limited in choice of carriers, because your b2bua support SIP reorigination only with media flow around.
I evaluated your company in depth. There is gap between what you talk about in presentations and demos and what can be accomplished in reality.13th November 2005 at 09:16 #30184Honza VomackaGuest

This is a pointless argument about definition of words:
PortaSIP = SIP server = SIP registrar + SIP proxy + B2BUA + RTP proxy + media server + others, all comes tighly integrated and is installed in less than 10 minutes.14th November 2005 at 21:03 #30185nonameGuest
I believe it is you who is missing the point.
No one buys a product just because it installs fast. It also need to give some value.
In the case of PortaSIP, with the limits stated earlier in this thread, not only it does not give value, it breaks important functionality that cab be achieved without it.
It is better (and cheaper) to use SER for SIP Proxy + Registrar and Cisco for b2bua + media proxy + media server.17th July 2007 at 20:43 #30186LawerenceGuest

CISCO As5300 support SIP. You need to config Sip-Ua and dial peer.
