Greetings Everyone!

We are using:
ViciBox V.10.0.0 210901
VICIDial version: 2.14b0.5
Asterisk #: 13.38.2
SVN: 3693
On physical computer Dell precision T1650 Intel i5, 16G RAM, 1 TB HDD

We have a Dialplan set for all the extensions under ADMIN->CARRIERS and one of the entry for ext 3290 is:
exten => 3290,1,AGI(agi://127.0.0.1:4577/call_log)
exten => 3290,n,AGI(agi-NVA_recording.agi,BOTH------Y---Y---Y)
exten => 3290,n,Playback(/var/lib/asterisk/sounds/44048020)
exten => 3290,n,Playback(/var/lib/asterisk/sounds/85100075)
exten => 3290,n,Dial(SIP/290&SIP/1290,15,Ttr)
exten => 3290,n,Playback(/var/lib/asterisk/sounds/85100031)
exten => 3290,n,Dial(SIP/290&SIP/1290&SIP/516&SIP/1516&SIP/806&SIP/1806,15,Ttr)
exten => 3290,n,Playback(/var/spool/asterisk/voicemail/default/290/unavail)
exten => 3290,n,VoiceMail(290@default)

From what I understand exten => 3290,n,Dial(SIP/290&SIP/1290&SIP/516&SIP/1516&SIP/806&SIP/1806,15,Ttr) actually works as a spillover and would dial all the mentioned extensions... Now here's the problem we don't have any dialplan entry for Ext 402 but for some reason whenever we call x3290 it is ringing 402.
Here's the result I have got after running asterisk -r :

Executing [3290@default:7] Dial("SIP/vitel-inbound-0004af2e", "SIP/290&SIP/1290&SIP/402&SIP/516&SIP/1516&SIP/806&SIP/1806,15,Ttr") in new stack

Any idea how to get rid of 402 in there as our DIalplane doesn't have and already tried reloading Dialplan script?
