[Asterisk-Users] T1 E&M false busy after dial

[John Ackley]

thanks info and suggestion
we have a plain old PBX DID trunk from our telco
will try to get more information about the trunk
meanwhile I tried as documented in my zapata.conf:

; JNA tried all below - and even NO signaling same resuts
;Apr 24 21:11:15 WARNING[4430]: chan_zap.c:10198 setup_zap: Ignoring 
:signalling
;-- Reconfigured channel 1, Feature Group B (MF) signalling
; etc.
;
;signalling=featb
:signalling=em_w
;signalling=sf_featb
;signalling=sf_featdmf
;signalling=sf
