How many devices have to keep the asterisk?

There is a member of the group sales, which phone rings when a customer calls.
When an incoming call comes to slogans, then start ringing the phones of all managers. And between these 2 stages have been put on pause, sometimes up to 20 seconds. At this time the client is in the tube there is silence, and phone numbers of managers don't call.
The outsourcing company, which is engaged in the service of Astera says that the problem is in the poll status of devices. The group now in their 30's

I can tell it is normal that such a number of devices have problems?

no not normal and I mean a survey of the status? they are all registered, when an incoming smoke customer spreads an IVR and if he didn't dial it the call goes to ring group managers (300) all played the entire rooms 301-308 begins to ring the phone.

ask them for a specific output the sip logs. just remember to wipe rooms
Just not all and according to the strategy. It can be in the queue - eunice_Kessler53 commented on March 19th 20 at 08:40

We have freepbx, 250 managers a bunch of groups. PBX on virtual reality. No such problems.
What you wrote - accident.
And how many at you a maximum in one group? - Gregoria10 commented on March 19th 20 at 08:42
20. - eunice_Kessler53 commented on March 19th 20 at 08:45
I even think that it is a problem of IVR. For example it is 10 seconds waiting for extension dial and goes no further. - eunice_Kessler53 commented on March 19th 20 at 08:48
