Hi, I'm wondering if anyone has recent experience using FreeSWITCH 1.10 on Debian 10 with libsng_isdn. I'm compiling from source and getting the errors below. I installed the current libsng_isdn, which is version 8.3.4. However, the FreeTDM instructions <https://freeswitch.org/confluence/display/FREESWITCH/FreeTDM> mention I need 1.2.0+ which makes me wonder whether these instructions might be outdated. Would an alternative be to just install DAHDI + libpri? I haven't tried that yet but would be happy to. This is all kind of new to me and I'm not entirely sure which components perform which tasks. I have wanpipe installed and am using a PRI/E1 line, I can see that my first port is connected (service wanrouter status), the card is a Sangoma A104. If I uninstall libsng_isdn I'm able to build and install FreeSWITCH with mod_freetdm but the errors below seem to be blocking me when I try to set it up with an ISDN library.
