SA Busy Tones

[beesknieg]

Guys, i have a Grandstream GXE5028 acting as a Gateway to my AsteriskPBX, calls get dropped after about 30 seconds over the Grandstream and i know my problem is with the Busy tones can anyone provide me with this info

Here are my current settings :
Dial Tone - f1=380@-24,f2=415@-24,c=0
Ringback Tone - f1=400@-24,f2=365@-24,c=420/1980/420/180
Busy Tone - f1=400@-24,c=500/500

And also another problem i just can seem so resolve :

I have a Vodacom SIP, phoning to another Vodacom SIP (087XXXXXX ) and the call will always drop at exactly 45 seconds, I have checked my NAT, Fireweall Asterisk etc.

Here are my SIP trunk Settings :

[2787XXXXXXX]
disallow=all
username=2787XXXXXXX
type=friend
secret=Mypassword
qualify=yes
nat=yes
insecure=invite,port
host=41.0.26.166
dtmfmode=RFC2833
context=from-trunk
allow=g729


BTW the PBX does the PPP to Vodacom

Busy tone: Don't waste your time with analogue, convert to ISDN or SIP.

Calls dropping on Vodacom: probably not getting SIP packets back in again. Turn on the SIP debugging in Asterisk and do some troubleshooting. This post covers the problem I'm referring too: http://stackoverflow.com/questions/23050268/asterisk-call-drop-after-30-seconds

Maybe this will help.

I am moving to ISDN though.

Thank you for the reply, after your suggestions I had a look at ISDN I think we will be converting

What ISDN gateway would you suggest, my PBX is in a Virtual environment so I can’t use the Digium cards directly on it

Thank you for the post but have tried these tones a while back and those hangup tones doesnt even allow me to make a call it just rings once and i get a hangup

The Patton gateways are pretty good, a little complicated to setup, but they work well.

These are really just Quintums with new branding

I see digium also has the Hyrid cards as well.
