Here are some Ideas I have -

I would be willing to let the group go over and correct my extension.conf file, I have been dealing with the fallout of ejo's talk on context security and would be happy to share a before and after.

It also seems that we have some people attending that are interested but have no experience with Asterisk. We could bring in a *nix box and build an Asterisk server during the meeting, this might be a fun activity? Especially if we use someones suggestion to "advertise" to the twin cities linux user group, show em how quick and easy it is to get started?

Please add your ideas!!


More ideas. Some of these could/will be covered with the current schedule.

  • IP quality of service issues/experiences (Linux traffic control/multiple queues, TOS bits, how to give voice packets priority over bulk data (especially when the ISP can't/won't implement any sort of QoS), etc.)

  • VoIP call quality issues — what can be done to attempt to work around a flaky net connection (marginal DSL line, congested cable modem, etc.)?

  • Which codecs sound good, and which ones should be avoided? Do users notice the difference? If so, do they care? Do callers notice the difference?

  • Is it worth paying the $10/channel g.729 patent royalty? Do you lose access to GPLed extensions & patches when you do this? What licensing issues exist with other codecs (g.723)? Are there viable non-patented alternatives with similar bandwidth usage?

  • Ways to track down and eliminate echo, both for local (intra-system) and external (POTS, T1 and/or SIP/IAX) calls.

  • Ways to support overhead paging, any experiences with the various methods (console sound card (including limitations of typical motherboard integrated sound), external FXO/FXS paging interfaces, etc.) How to play an attention sound before the page (is it possible to make it audible to the caller doing the page as well as over the system?)

  • If you use analog POTS lines, how hard is it to calibrate tx and rx gain? Which patches are needed for Asterisk and the Zaptel drivers? Has anyone used milliwatt test lines and the ztmonitor quantitative display patch to do this calibration, or do you do it by ear and merely estimate appropriate levels through trial and error?

  • Experiences with various VoIP providers — which ones have worked well, and which ones should be avoided? What billing method is better for which purpose, flat-rate, prepaid, something else? Which providers make their services easy to use with Asterisk, and which discourage (or flatly disallow) use of anything except a device they provide? Which providers go too far in attempting to emulate a POTS line (by prohibiting multiple simultaneous calls, etc.) and which ones are flexible?

  • Advantages/disadvantages of different types of phone hardware (analog, ADSI, SIP (which brands?), etc.) How hard is it to get working message waiting indicators on various types of phones?

  • Advantages/disadvantages of different types of phone device interfaces (Digium FXO/FXS ports, T1 cards and channel banks w/ FXO and/or FXS ports, IP phones of various types, etc.)

  • Experiences with various types of PSTN connectivity (analog POTS to FXO ports, voice T1, BRI or PRI ISDN, etc.) When does it make sense to use each one?

  • Integrating multiple sites into a unified system (manual SIP/IAX forwarding, DUNDI, other methods?)

  • Web administration interfaces — which ones are worth using? What can and can't be done with them? How well do they deal with hand-tweaked config files? (After all, non-technical managers would like to be able to do basic tasks, even if you got hit by a bus.)

  • User training issues — which features do users easily grasp? Which ones do they not understand at all even after a long lecture? Can these hard-to-understand features be made any easier for average users? Are they needed at all? If your user base is not technically literate, which features should you tell them about, and which ones will only confuse them more? Are certain features significantly easier or harder to use with some access devices (SIP phones, ADSI phones) than others (analog phones)?

  • How serious a problem is SPIT (unsolicited commercial calls)? Is it bad enough to think twice about setting up DNS SRV records for your domain and/or allowing anonymous SIP or IAX connections? How can it be avoided?

  • Compare and contrast SIP, IAX2 and other lesser-used VoIP protocols (H.323, MGCP, SCCP) — what are the advantages/disadvantages of each? When should each one be used? When should each one NOT be used?
