Hi,
I have the following situation: At a branch , there is a Cisco Call Manager with users all having
Cisco phones. Now I put down a Asterisk 1.2.12 box at the branch, which talks H323 via chan_oh323
to the CCM. So calls go from the CCM, go H323 to the local Asterisk box, then I take it via SIP to
another Asterisk box. From there I am hooked up to 2 different providers, for Local and
International, both via SIP. The problem I am having is that the users dont get ringback (ringing
indication) when they dial International numbers, yet it works perfectly when they dial Local
numbers. Yet, to test, from a hardphone plugged into Asterisk2, I get ringback, so its not the
Interntional provider, it must be the SIP trunk from Asterisk1 to Astrisk2.
(ringback)

H323 SIP | SIP
(no ringback)

ZAP hardphone
Here is the sip.conf from Asterisk1.
[N_G]
type=friend
host=10.255.255.1
username=N_G
secret=N_G
disallow=all
allow=g729
canreinvite=no
qualify=yes
progressinband=yes (tried this yes/no/never, made no difference)
When I call goes from Asterisk1 to Asterisk2, I get the 'making progress passing it to xxx', but I
dont hear ringing, then the person answers.
