Hello,
I�m compiling a table of features supported in SER, such table will be helpful to compare
SER capabilities with other SIP proxy servers.
Keep in mind that's a hard job. Some of the features may be
end-device feature and some may have different mimics than
you would expect. Also, it is not only specific telephony
features which matter: importantly, there are things such
as operational characteristics (performance, scalability)
and ability to introduce new features and integrate with web.
* Private number (permanent Caller-ID blocking):
A way I do maintain privacy is I use a stupid user id
(You certainly know how much identity is dislocsed if you
send from mr_goerge_w_bush(a)hotmail.com....)
* Caller-ID blocking per call (like Bell *67):
see above, a phone may maintain multiple identities, one of
them less informational than the other one.
* Caller blocking:
Yes -- we block requests from source causing annoying traffic.
* Call Waiting (support more than one call):
phone feature (see for example www.iptel.org/tt/ for such a phone)
* International routing dial plan:
* Least-cost routing:
all trivial config options
* URI/Phone manipulation: Yes
* Find-me parallel calling: No
find-me is built-in (known under the SIP term "parallel forking")
* Find-me consecutive calling: No
unavailable now
* Call Transfer:
phone feature
* Conference Calls (3-way calling): Yes
* NAT STUN: Yes
just for sake of clarity: we have a STUN impelmentation,
but it is separate from SER
* Billing Flat-file CDR: Yes
* Authentication: Yes
* Authorization: Yes
* RADIUS authentication/Authorization: Yes
* RADIUS accounting: Yes
* Support for call time limit:
call-limitation is part of separate software
* ENUM support : Yes
* IM&P (Instant Messaging and presence): Yes (2G/SMS, SIMPLE/XMPP Jabber)
* WEB Provisioning Interfaces: Yes
* Programming interface to remotely provision from an OSS system (add/remove/modify
user/settings):
provisioning available as command-line or web tools
* Programming interface to remotely modify system
settings from an OSS system (routing rules, gateways, etc.):
available as server configuration options
* Redundant server configuration:
available as separate softwarea
* Call return (like Bell *69):
* Call screening:
see missed calls and click-to-dial in SERweb
* MWI (SIP NOTIFY):
not now
