Asterisk + HiPath 3000

Hi there.
I am trying to set up HiPath3800 with Asterisk over IP.
I have been searching , but there is almost nothing regarding this.
I am pretty familiar with the Hipath 3000 systems, but not the asterisk.
I’ve copied the only thing found in google.
The settings are:

hg1500sip type=peer host= canrenvite=yes insecure=very qualify=no nat=no disallow=all allow=alaw allow=ulaw context=default

macro-tohg1500 exten => s,1,Answer() exten => s,2,Dial(SIP/${ARG1}@hg1500sip,30,tTr) exten => s,3,Goto(s-${DIALSTATUS},1) exten => s,4,Hangup() exten => t,1,Hangup() exten => T,1,Hangup() exten => h,1,Hangup() exten => s-BUSY,1,Playback(the-party-you-are-calling) exten => s-BUSY,2,Playback(is-curntly-busy) exten => s-BUSY,3,Goto(s,4) exten => s-CONGESTION,1,Playback(the-party-you-are-calling) exten => s-CONGESTION,2,Playback(is-curntly-unavail) exten => s-CONGESTION,3,Goto(s,4) exten => _s-.,1,Goto(s-BUSY,1) exten => _.,1,Goto(s,4) default exten => 209,1,Goto(mainmenu,s,1) exten => _5.,1,Macro(tohg1500,${EXTEN})

I set the extensions at the HiPath to be 5xx range as the example showed.
Still when trying do dial any number with 5xx from registered client at the asterisk side I receive "Cannot be found"
At the HiPath side I am monitoring the trunk ( which shows UP by the way) and there is nothing incoming when I dial.
To dial from the HiPath to asterisk is also impossible.
My asterisk is 1.6

I will appreciate any help with this.

PS. I’ve got to the conclusion that there is something to set in asterisk , because at least a garbage shoulf be received at HiPath’s side.

Iam also trying to connect Hipath 4000 to asterisk.

I got a documentation from google.

give me a test mail to…i will forward it…
