Dialplan Help with GoAutoDial

[jnharte1973]

I was wondering if the dialplan was correct. I'm taking over someone else's mistakes and need to know why my station agents are not getting predictive dialing to work, seems like we can do it Manually through GoAutoDial, using Zoiper Classic. The person who took care of it last had switched it from SIP to IAX and I'm not sure if he input the dialplan info correctly. Here is the basic Vicidial info:

3 Stations in total
Proxmox: Virtual Environment Version 2.1.1/f9b0f63a
Vicidial VERSION: 2.4b0.5
Server ID: Vicidial
Name: Vicidial Single Server (1 Server)
Server IP: 192.168.0.234
Active: Y
Asterisk: 1.4.39.1-vici
Trunks: 96
GMT: -5

Dialplan Info:

Carrier ID: iaxgoautodial
Carrier Name: sipgoautodial
Carrier Description: sipgoautodial mod
Registration String: register => 2012969901:n3Fs81GyLv@dal.justgovoip.com:5060/2012969901
Protocol: IAX2
Globals String: GOAUTODIALIAXTRUNK = IAX2/iaxgoautodial

*This is what I think is wrong, but I'm not sure
DialPlan:
exten => _91NXXNXXXXXX.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _91NXXNXXXXXX.,n,Dial(SIP/${EXTEN:1}@justgovoip,,tTo)
exten => _91NXXNXXXXXX.,n,Hangup

Server: 192.168.0.234
Active: Y

I'm also getting this message when updating users:
Could not connect: 192.168.1.2|vtigercrm510|vtiger|vtuser

Any help or tips would be highly appreciated,

Thank You

1.
register => 2012969901:n3Fs81GyLv@dal.justgovoip.com:5060/2012969901

as you have mentioned IAX then the port should be 4569 instead of 5060 in the above line

check with justgovoip.com whether it is SIP or IAX protocol trunk

2.
exten => _91NXXNXXXXXX.,n,Dial(SIP/${EXTEN:1}@justgovoip,,tTo)

again you mentiond protocol as IAX then you should use IAX2 instead of SIP
exten => _91NXXNXXXXXX.,n,Dial(IAX2/${EXTEN:1}@justgovoip,,tTo)

Could not connect: 192.168.1.2|vtigercrm510|vtiger|vtuser

go to ADMIN-system settings,
disable Vtiger
ie : Enable Vtiger Integration : 0
