This features usefull for example in next situation:
A calls B. When conversation complete A and B disconnects from network
(unplug cable for example) and OpenSer never gets "BYE" and this call
cann't be acounted properly.
-- allow Openser to be SBC. Now we can use OpenSER for this with some
gymnastic in rewriting of request and response body using avpops
module, But it's really difficult to write and support this config.
New OpenSER module (may be) called SBC can do all this work with
interaction some other modules (RR, TM and others). This module must
rewrite SIP messages to mask all internal resources for outgoing
(relative to OpenSER) messages and rewrite all incoming messages to be
appropriate of outgoing messages.
What do you mean with SBC? SBC typically have dozens of features (NAT,
...). Do you mean topology hiding or an other feature?
The primary goal is to hide topology and send all SIP traffic through
OpenSER. Now we can rewrite Contact: (not only for NATed devices but for
all), RURI and some over headers from config and mask addresses in this
way. We can add RR also. But it's really difficult and sometimes
impossible to rewrite all headers. Smart module which allow to work
OpenSER in SBC-only mode and do it automatically may be useful in this
situations.
-- (dreams) SIP-H.323 converter. I know that many of such converters
exists in real world (one of famous and commonly used is Asterisk).
But I think that native OpenSER SIP-H.323 converter can helpto OpenSER
to be more useful. If somebody familiar with H.323 he can write this
module based on OpenSER Dialog module
There is already Asterisk, yate, freeswitch ... this IMO we should fokus
on SIP.
yes, you are right. We must do one thing but do it perfect.
My idea is convert SIP-H323 on one hop/host and don't use anything over
OpenSER
Thanks
