Call dropouts when other party answers

Hey all.

Ive been trying to figure out why my outgoing calls just drop out on answering.

Ives tried two different modems.

Ive also tried installing ASterisk 13 and 11 but the same thing still happends.

Upgraded the firmware on a brand new adsl2+ modem…still got problems.

Might note that im not sure if port forwarding needs enabling, however at the moment it is disabled.

Theres are my peer details, however there is nothing entered in the user details box.

host=sip.simtex.com.au
username=(usernameremoved)
secret=(passwordremoved)
type=peer
context=from-trunk
insecure=very
qualify=yes
canreinvite=yes (makes no differnce if yes or no)
port=5060
dtmfmode=inband
pedantic=no (also makes no difference)

I’m using Cisco 7940 Telephones with SIP.

Not sure what to do, just wondering if anyone could help.

Thanks.

heres my log with sip debugging enabled just after a failed call.
