Connecting Asterisk with a legacy PBX

Postby gu33mis » Mon Nov 23, 2015 9:13 am

I'm trying to connect Asterisk with our existing PBX system (quite an old one), but for some reason inbound calls from from the PBX are not showing any calling or called numbers and appear on CLI as:

-- Accepting call from '' to 's' on channel 0/30, span 1
-- Executing [s@pbx-index:1] Answer("DAHDI/i1/-1", "") in new stack
-- Auto fallthrough, channel 'DAHDI/i1/-1' status is 'UNKNOWN'
-- Hungup 'DAHDI/i1/-1'
-- Accepting call from '' to 's' on channel 0/31, span 1
-- Executing [s@pbx-index:1] Answer("DAHDI/i1/-2", "") in new stack
-- Auto fallthrough, channel 'DAHDI/i1/-2' status is 'UNKNOWN'
-- Hungup 'DAHDI/i1/-2'

If I try to dial any legacy PBX extensions form a phone registered to Asterisk everything is working fine, but not the other way around.

I will appreciate any help.
