Issues forwarding hunt group to blast group

Hi guys,

Last night, I tried replacing some of our shared lines with blast groups. Currently, our UC520 is set up with hunt groups that first ring a single phone, then ring a shared line and finally ring the original person, forwarding to voicemail if not picked up.

This system is inefficient as only 1 call can be on the shared line at one time.

I created a blast group last night with 3 phones added (using the CCA v2) which added the following code,

"voice hunt-group 1 parallel
final 101
list 924,925,951
timeout 5
pilot 507
"

That works fine. I then created a hunt group which would ring a single phone then end on a blast group (it seems like hunt groups can't do Single phone->Blast group-> single phone in a single hunt) which gave me this,

ephone-hunt 5 sequential
pilot 805
list 925
final 507
preference 0 secondary 7
timeout 8
!

Ringing the blast group directly works fine but when we tested ringing 805, it failed when it was supposed to ring the blast group. We checked over the settings for a good few hours, trying to work out why this didn't work but we didn't get anywhere.

This seemed like the logical way to me but is there another way I should be going about this?
