SIP Account not registering with 3.8.9.1_BT

I just tried upgrading my 2860Vac to 3.8.9.1_BT and found that it wasn't logging on to the SIP server (A&A).<br/>
As it's our main phone I downgraded back to 3.8.8_BT rather than dig too much, and that logged immediately into the SIP server.<br/>
<br/>
Has anyone else tried that upgrade and had issues? Or conversely upgraded and had no issues (in which case I'll try again).<br/>
<br/>
It's unlikely to make a difference, but the WAN is actually via WAN2 PPPoE via a 130 at the moment as the 2860 wasn't syncing on the line for some reason.

I think you mean 3.8.1.9 rather than 3.8.9.1? Yes, I have that exact same problem - upgraded to 3.8.1.9 and SIP trunk stops working. I am just about to try downgrading to 3.8.1.8 to see if that fixes it.

Yes, can confirm that 3.8.1.8 works fine but 3.8.1.9 does not.

He's using a Vigor 2860Vac for which the current firmware version is 3.8.9.1<br/>

You're right, of course. A coincidence that the numbers of the faulty firmware are the same just in a different order! <br/>
<br/>
Mine is a BX2000 and, as you say, his is a 2860Vac.

I've got the same problem with a new 2862Vac, I can't get the router to register with the A&A SIP server.<br/>
I've tried firmware versions 3.8.6.2_BT and 3.9.0_BT.<br/>

Glad it's not just me. Thought I was being stupid.<br/>
Not so glad it's not working though.
