establishing audio incoming group call

[Edty]

Hi All,

I have 4 handsets registered with 4 sip registrations (each handset its own registration) and connected with the W52.

These accounts can be called simultaneous in a hunt-group call (broadsoft).
When being called as simultaneous hunt-group, all handsets get alerted. After answering one of the handsets, it takes almost 3-4 seconds before the audio gets established.

In case only one account is called, this problem does not occur at all. It almost seems that, the more accounts are being called in this simultaneous group call, the longer it takes before the audio is connected.

In this scenario the time it takes to have the audio connected with 2 calls, is more ore less acceptable, so we've temporally placed a second base-station with two handsets / accounts each.

Is this a familiar issue, how can i solve this problem?

Warm regards,

Edty
