Hello,

we are experiencing unexpected call droppings, always after exactly 176 seconds. This only happens with calls from VoIP to a Panasonic pbx 1232. Calling from VoIP anywhere besides to the pbx, (mobile phone, other outside line), this does not happen. Might it be something with the pbx or with the router?

I pasted an example of router debug below.

Thanks for your help,

Thomas Liss
