Hi,
I have a problem with a SIP trunk between Asterisk and central OXE Alcatel,
especially sometimes are not received inbound calls with following messages:
-- Executing [...@test:1] AGI("SIP/800-084250f8",
"agi://127.0.0.1/test.agi") in new stack
-- AGI Script agi://127.0.0.1/test.agi completed, returning 0
== Auto fallthrough, channel 'SIP/800-084250f8' status is 'UNKNOWN'
I configured the sip.conf file:
[800]
type=peer
host=172.XX.XX.XX
username=test
secret=XXXXXXX
insecure=very
context=test
disallow=all
allow=alaw
allow=ulaw
and the extensions.conf file:
exten => 375,1,AGI(agi://127.0.0.1/test.agi)
I attach to this email the sip messages receveid by Asterisk when the
problem occurs.
Thanks for your help.
Best regards,
GP
