Hi,
some weeks ago I followed a discussion on this list ("Using mISDN with recent asterisk and Debian") that encouraged me trying to get asterisk working on a raspberrypi together with mISDN, CAPI and chan_capi.
While capiinfo seems to report success (see below), asterisk gives me the following messages on startup:
[2017-09-17 18:55:19] VERBOSE[1822] loader.c: Loading chan_capi.so.
[2017-09-17 18:55:19] VERBOSE[1822] config.c: Parsing '/etc/asterisk/capi.conf': Found
[2017-09-17 18:55:19] WARNING[1822] chan_capi.c: CAPI not installed, chan_capi disabled!
[2017-09-17 18:55:19] VERBOSE[1822] loader.c: chan_capi.so => (Common ISDN API Driver ($Revision: 963 $))
Has anyone on this list an idea what might have gone wrong?
Btw. there is no device /dev/capi*, but I thought this not needed anymore with mISDN V2?
Any help is appreciated, please have a look at the info below.
Cheers Jan
This is what I have done:
- Installed RASPBX on the raspberrypi, it comes with asterisk 13.15.0 (after upgrade of the distro).
- compiled mISDN, libcapi and capiinfo from isdn4k-utils (https://github.com/b1-systems/mISDN.git + mISDNuser.git)
- compiled chan_capi (tp://ftp.chan-capi.org/chan-capi)
I followed the hints on:
https://www.misdn.eu/wiki/Howto_for_Debian/
https://www.misdn.eu/wiki/Capi/
http://www.melware.org/ChanCapi
Here is some information about the system:
