Notes from SEMSi [1] users meeting at VON Europe fall 2006
keywords:
+ SEMS and *
+ SERi [2] - SEMS
+ Performance
+ Python/IVRi [3]
+ wishlist
SEMS and *:
- why have two F/OSS media servers?
-> * is PBXi [4] and feature for everything
-> SEMS for high call count and simple functionality
- have * tell SEMS to send RTPi [5] streams using a midcom-like
protocol (similar to mgcp) would enable a */SEMS combination
to handle a lot more calls
SER - SEMS:
- Bogdan Pintea presented the idea behind new SER-external
application interface
- expected: * performance improvement
* more flexible: new callflows possible
e.g. sending ACK with SDPi [6] answer from SEMS
* eases configuration: SEMS tells SER which data
it expects
Performance:
- failures/timeouts on unix socket observed with high throughput
(Alexandr)
- ports not freed? (-> bug tracker, Alexandr)
- FR: preencoded announcements (also: licensing, Bayan)
- user vs. kernel space:
IVR/Python:
- the name 'IVR' misleading: its actually powerful scripting system
- future: * 'ivr' module with simple, clear defined API
(current 'ivr')
* 'scripting' ('pysems') module with generated wrappers
exporting all framework functionality (pysip branchi [7] ivr)
- python application repositoryi [8] on web-site and SVN needed
- atle & bayan write python app that executes ivr menu read
from db
wishlist:
- video (->licensing?)
- T.38 fax
- dialout documented
- SIP stack as module in SEMS (->independent from SER)
