I was using the Mad Boss example and I was getting parse errors, I traced it down to the following line, <action application="conference_set_auto_outcall" data="${group_call(sales)}"/> when group_call gets expanded it adds the default dial string for each member of the group which ends up looking something like this. [sip_invite_domain=10.195.94.25,presence_id=1001@xxx.xxx.xxx.xxx]sofia/internal/sip:1001@xxx.xxx.xxx.xxx, [sip_invite_domain=10.195.94.25]error/user_not_registered The parse error I got "Cannot create outgoing channel of type [presence_id=1003@10.195.94.25]error cause: [CHAN_NOT_IMPLEMENTED]" indicated that it was treating the comma inside the brackets as a separator between 2 dial strings. I worked around this for now by editing the default config for the directory to remove presence_id from the dial string and it's working. This appears to be a bug in the parser as I was getting this error with the default configurations. Thanks, Duvid Rottenberg
