Lost connection with GAP mobile

[jpissot]

Hi,

We have a new customer with :
- OTBE (R2.2.1) on SITE A
- MG WITH T2 TRUNK on SITE A
- IBS base station (x8)
- mobile 8232s
- mobile GAP (gigaset)

There is no problem

But , on the site B :
- MG with T0 accesses
- IBS base station (x6)
- mobile 8232s
- mobile GAP (gigaset)

There is no problem with mobile 8232s, but with the gigaset (same modele that on site A), the mobiles lose the network a dozen faith per day, for a few seconds. If the user is in call, the call is disconnected.

T2 access is configured with synchro 200, and the T0 accesses with synchro 210.

The link between the 2 sites, is a VPN SSL.

Thank you in advance for your help
