SIP - HG - Twinning issue

[j.flanagan]

I have a customer that has an IP500v2 on 9.1.
Due to this Covid 19 thing, they're wanting to work from home as much as possible.
So, I set up twinning so that they can answer calls from their cell phones.

They have a sip line
Main number goes from the incoming call rout to their Main Answer Group
There are 3 users in the main group that have mobility turned on and mobile twinning.
The issue is that when I watch System Status, i can see the system alert all 3 users and then it twins to only 2 of their cell numbers. If I repeatedly call, it seems to twin out to A/B, B/C, C/A, A/B and so on. But systematically to just two users, rotating through which 2 it is calling.

The hunt group is set up to collectively ring with no queuing.

How can i get all 3 to be called at the same time?

Probably a SIP trace will give some insight.

I guess the provider drops some calls for whatever reason. Too less channels?

IP Office remote service
Fixed price SIP trunk configuration
CLI based call blocking
SCN fallback over PSTN

How many SIP channels are in the trunk to the carrier? How many SIP channel licenses are there?
Can you confirm this in system status?

I've reached out to the customer, hopefully they will get back to me shortly regarding how many channels they are being provided with. As far as licensing, they have 25 sip channel licenses. I will see if I can get a monitor trace on the sip calls.

In the Mobile Twinning section, make sure you toggle on "Hunt group calls eligible for mobile twinning"

Thanks for the pointer, I do have that one checked already though.

Collective HG's are not twinning ALL users out.
The IP Office is not designed to do that to ensure that not all lines are taken by a single call into a HG.

You have to be lucky if there are more than 1 user twinning
