John, Okay, a few things. First off, the wanpipe2.conf file has a booboo. This line is WRONG: TDMV_DCHAN = 0 For ISDN in North America you want: TDMV_DCHAN = 24 Also, I recommend changing this line: wbg1 = wanpipe2, , TDM_VOICE, Comment To this: wbg1 = wanpipe2, , TDM_VOICE_API, Comment A sample config for Sangoma wanpipeX.conf is here: http://wiki.freeswitch.org/wiki/OpenZAP#Wanpipe_mode Okay, ISDN 101: there is a "network" side and a "user" side. (Also called "terminal" or "cpe"). From what I see here you are trying to have FS be the network side and the Cisco is the user side. Assuming that this is what you want then you will need to use ozmod_libpri because the default OpenZAP PRI stack does not currently support being the network side. You will need to download and install libpri from downloads.digium.com and then you'll need to reconfigure openzap. Follow these instructions to get libpri and openzap working together: http://wiki.freeswitch.org/wiki/OpenZAP#Adding_libpri_Support And then check out this example openzap.conf.xml file for using libpri: http://wiki.freeswitch.org/wiki/Openzap.conf.xml_Examples#Using_with_PRI_.28... (Note that you don't want 'cpe' here but rather 'network'.) Now, on the Cisco side... sorry, can't help you. However, I don't see any glaring gotchas from looking at the configs. I don't see where timing is specified nor do I see where the d channel is specified. Hopefully you can confirm that those are set properly. (The cisco needs to be a "slave" to the FS clock, also called "receiving clock"; d-channel is 23 or 24 depending on how cisco numbers their channels.) Have fun! :) -MC On Tue, Apr 7, 2009 at 5:37 PM, John Wehle <john@feith.com> wrote:
Our FreeSWITCH setup has an existing T1 using RBS to talk to a digital modem pack in a Cisco 3845. I'm interested in changing from RBS to ISDN. I changed both sides, restart things, and see FreeSWITCH report:
