Exporting variables through mod_fifo/mod_callcenter & codec issue in mod_fifo
Hi I am trying to export some variables to consumers (mod_fifo) or callback agents (mod_callcenter). The basic scenario I am trying to achieve is to associate some data with path taken in IVR (in form of exported variable) and pass information on which option was chosen in IVR to the agent. I took a look at the source to find out how mod_fifo/mod_callcenter originate calls to consumer/callback agents and it seems the calls are not associated with A-leg (somebody calling to IVR and transferred to queue). Is it on purpose? Is there a workaround for that? I also spotted strange behavior of mod_fifo when originating calls to consumers. It sets absolute_codec_string for calls originated to consumers to variable_sip_use_codec_name from A-leg, adding PCMA/PCMU if not already present. I find the logic there quite puzzling. If somebody is calling to queue using e.g. G.729, mod_fifo will restrict codecs available in leg to consumer to only G.729, PCMA, PCMU. Why is this narrowing of choice of codecs implemented?

I was wondering if this e-mail hit the list or maybe I wasn't exactly clear on what I'm trying to achieve and that's why I got no answers. Best regards, Marcin 2012/2/16 Marcin Gozdalik <gozdal@gmail.com>
