Hello,
What does the following stat mean when you run the " openserctl moni "
sl: received_ACKs = xxxx
I did some digging and I got the following explanation... But am not sure if this is an error in operser or an error on a message received by openser or what?
" sl: received_ACKs - number of received ACKs due sending negative replies. "
any help is appreciated.
thanks, --Jignesh

when you send a negative reply (code >=300), the calling party sends an ACK. This ack is filtered by sl module (does not get in config file). This statistic counts them.
Typical case is authentication of calls or registration. The auth modules use sl to send back the challenge (401 or 408 replies).
Cheers, Daniel
Hello All,
Can openser be used as a SIP Application Server in an IMS infrastructure ?
Should I use Kamailio instead ?
thanks, --Jignesh

By definition a SIP proxy is not a "SIP Application Server"(which in most cases are B2BUA's). However if you mean a "IMS SIP proxy/registrar" then OpenSer/Kamailio could be valid (except for some custom requeriments of IMS). You can take a look to OpenIMS which is OpenSer/Kamailio with some "customization" or new modules designed for IMS.

Well, 'SIP proxy is not an SIP application server' is a bit forced. IMO, an application of SIP can be proxying SIP request, while most of the sites define couple of SIP server side entities like proxy, registrar, etc... these are just some types of applications for SIP.
On the other hand, Kamailio is more than a proxy and it is in fact a real application server. It cannot be a VoIP application server, since it does not do media processing, but can be a sip signaling application server and it is a lot you can do with signaling only (e.g., messaging, presence, custom communications and notifications).
This is indeed an app to look at, site is http://www.openimscore.org. AFAIK, they updated their code and practically they run same core and common modules as kamailio/ser 3.0
To give the proper answer to the question, then the kind of application wanted to be deployed must be described.
And kamailio is just the new name of openser, since there were some trademark issues with openser word. The sourceforge devel project still keeps openser name. Last version released under openser name was 1.3.x, the first under kamailio name was the next one 1.4.0. Version 3.0.x is the last stable one, with lot of enhancements since last version with openser name was released, see here what are the major enhancements coming with every release: http://www.kamailio.org/dokuwiki/doku.php#features
Cheers, Daniel

right, to some extent you can play with media in conjunction with rtpproxy -- iirc, you can do some audio playback with latest rtpproxy.
What would be the accelerator used for?
Thanks, Daniel
thank you for your reply.
Would you know of anything that can be used as a SIP Application Server with capability to do REFER, RE-Invites and parse SIP-I payload passed to the server.
OpenIMS has SIP AS as an external entity.
thanks, --Jignesh

Not out of the box. But probably you could to this by using the SIP_BODY function https://issues.asterisk.org/view.php?id=15552 and some external script.

Jignesh, note that these days when you are talking about Kamailio and OpenSER, they are one and the same.
