This type of data is useful and helpful in trying to continue to improve chan_pjsip. As far as contingent actions (such as marking chan_sip as deprecated) my opinion is that they are still premature - as mentioned in my other reply.

I would argue that there are many more modules in Asterisk's code base that have less maintenance than chan_sip but are still permitted to be there.

The codecs then could presumably act on that behavior (increasing FEC level, reducing bitrate, etc).

[asterisk-dev] Adding a new module to Asterisk
Hi All, I'm in the process of adding a new module to Asterisk, in this case, a new CDR backend. The new backend relies on a library that I need to introduce to the linker, however, I've tried to figure out how the autotools work in there - and had failed miserably. I would appreciate if someone can shed a little light on the process - if possible.

[asterisk-dev] Asterisk 14 Security Fix Only Mode
Hey all, For those who may not be aware Asterisk 14 transitioned from bug fix mode to security-fix-only mode a few weeks ago (Sept 26th). For those of you that are still on this release, it's a good time to consider building an upgrade plan for moving to 15.x.x. I sincerely apologize for the late notification. Somehow, this was overlooked in the push to get 15.0.0 released. You can read more about this process and the relevant dates on the wiki at https://wiki.asterisk.org/wiki/display/AST/Asterisk+Versions Best wishes, and sorry again about the confusion on this. -- Matthew Fredrickson Digium, Inc. | Engineering Manager 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-dev mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-dev
