[Freeswitch-users] Asterisk to FreeSWITCH migration guide

Tue Aug 16 02:17:19 MSD 2011

Anthony,

My gripe was not about simply having a DIALSTATUS variable in Freeswitch which copies what is from "originate_disposition" what I wanted is to be able to get the status of the B-Leg because right now when early media is played (which i wanted)  "originate_disposition" shows "ANSWER" which I think is caused by me explitly called the "answer" app in my dialplan before the bridge app, this is because my DID provider requires an answer/sip 200 or else it will keep re-sending the sip invite, therefore causing freeswitch to keep creating new channels. All I want is to be able to get the proper sip/hangup/dial statuses of the B-leg.

=D 

ok, sure.  If that's your only complaint.... see commit 9d98d49f0556fb79656c8403f285ae0a615439d3

Some caveats

1) There is actually less specific, more generalized data in this DIALSTATUS variable than what we already report, when you're ready to move on see the originate_disposition variable:  It's kind of like going from reporting the precise geo-location of a cafe in Paris to generalizing it to "EUROPE" 

We follow the Q.850 standard for call cause codes and follow the SIP RFC to map sip response codes to/from the Q.850 equivalent.  Also each module has its own version "sip_hangup_disposition" for sip so you have both the real sip response code AND the official Q.850 equiv variables set on each call.

2) We don't have a torture feature so we never return that code.

3) Since our originate can return before a call is answered I added "EARLY" which means the originate succeeded but its still not answered.

4) For any others that do not map directly to FreeSWITCH, I just installed a copy of originate_disposition for good measure.

P.S 

This email took longer to compose than the patch did while sitting in the middle of a crowded room so you probably could have simply parsed the originate originate_disposition yourself but if it helps people get over being stuck in a paradigm, it's worth it for me to write........

I find that Asterisk's AGI is much easier to use, they allow you to retrieve the dial status much easier than freeswitch's api's. Come on freeswitch, if you want to be better than asterisk, you should make it easier to get the dialstatus, etc. At this point asterisk is still defacto.

1.0.7
release appears as a package on the debian distribution, at the
beginning i was amazed by the fact i can build a PBX for my own
business
and i did, later i began to install this system for my customers and
sooner i meet the problems, however being the software open source i
always find a way to fix things using patchs from others, sometimes i
felt how my life was at risk when the system stops working and that
usually happens when i have to use queues and dealing with digium
hardware.

hardware where the digium cards were supposed to be installed helps me,
but that was to much stress for me and seeking for a balance that will
let me invest more time on services, configuration and hoping to have
better hardware
options brings me to freeswitch.

want.
