Hi all,

After upgrading the 2820ippbx to fw v3.5.7 we decided to set up a spare inbound sip trunk with auto attendant, pressing 1 forwards call to a hunt group. Within the hut group there are four ip desk phones, only one being a vigor 350 (running the very latest fw). In operation when an inbound call is forwarded to hunt group from auto attendant and call answered on vigor 350 the call is un intelligible almost like codec miss match or encrypted! if repeated but this time answering call from any other phone within the hunt group the call is heard with no problem.

Anyone experience this?
