If you can try this please,

1. Disconnect the DSL from your Router
2. Wait for the Phone LED's to go out on the 2102 (within 3 Minutes)
3. Reconnect the DSL to the router
4. See if the 2102 comes back on line

I have been monitoring my VFX lines last 3 days,

Scenario 0
I have had my VFX lines ( 3 Lines 2 accounts) dropping almost every day, these lines were using AG300 modem/ router, every time the line drops I have to use Maverick's suggestion above which restores the VFX line. I have occasions my wife dials through Internationals calls via Telecom not releasing the VFX is down.

Scenario 1
I have replaced the AG300 with 3COM 3CRWDR100A all 3 lines are using this router all lines registred went to bed, got up in the morning the 2 lines on the SPA2102 are dropped. Okay Restart the 3COM router went to work come in the evening the Line on the SPA3102 dropped.

Scenario 2

Decided to use my TCNZ broadband for SPA2102, which is using 3COM 3CRWDR100A, and SPA3102 with FUSION using identical 3COM 3CRWDR100A, this change over happened last night, got up this morning hmmm both the VFX devices are registered and up. but in the evening the line on the SPA3102 is dropped which is using Fusion.

Not only this time... but also I have recollection VFX always worked with TCNZ broadband....with Fusion its always drops.

I will not put this to a Firewall port issue, most of these ADSL router Firewall ports are open (All ports) to outside world, unless you specifically block them. If my SPA devices made a successful registration this means they have allocated them the port they wanted. There is no Fusion line going down or Router restarts caused this. I'm sure WXC can see my VFX registrations in the logs.

I'm I missing something here....?? do I have to allocate a port to come IN for VFX.

DAY -4

SPA3102 - VFX lines gone down, yea yea... one with FUSION, my other VFX line with TCNZ broadband registered and solid as rock.  This got to be something to do with the FUSION, this used to works for days in the early days when I join WXC, this line was registered when I went to bed, my ADSL logs shows there is no PPP fails, its simply dropping the VFX. 

Hmmmm, New Zealand always been a Testing ground for Software vendors and large Hardware manufacturers, are we all part of this?  this time a large electronic automation (PLC) manufacturer doing the rounds?

My things to do list for today....Hit the WXC help desk...and go aroung in circles

Note: The issue here won't actually be the connection but more a firewall port natting issue !!!

These are your currently registered lines point to Note the port they are both 5062 and 5063, now you may want to rethink your conclusions a little bit since the ports the device is sending is actually 5060 & 5061 so it IS being changed and quite possibly the pinholes may get closed after a certain time and does not NAT the 5062 back through to 5060, now this can be due to the Packet Type, UDP vs TCP it could be the connection reknewing DHCP leases breaking any NAT rules for packet types, it could changes of IP addresses,  registered  5062  registered  5063

What router is in front of this device is it presently the 3Com if it is does it have a SIP ALG setting ? in the mean time I have made a change on this box, so see how you go know,

You are missing a couple of things but you have to remember also, unless you can see what is happening on both sides of a router and you are actually looking at the packets and know what comes out of the device and also know what your looking for, you can very easlily jump to the wrong conclusions, 

I will take a look at the 3102 as well, no requirement to call the helpdesk at this point for that, what is the router in front of that at present the same 3Com ? 

And hopefully I won't go round in circles with this Wink

Yes I am a employee of WxC (My Profile) ... but I do have my own opinions as well Wink

Okay, 3COM has MODEM+ROUTER+FIREWALL+ SWITCH all built in, there are AGL settings I'm not using any. NAT is enabled and by default all ports open to outside world few standard ports are open inwards - this applies to both of my 3COM routers.

I agree I have to look at both ends which ports SPA devices are using.

I would like to leave the following account using SPA2102 with TCNZ broadband, as its now, this will eliminate or reduce the chances port conflicts etc.  registered  5062  registered  5063

The other Device SPA3102 phone 099xxx4 will use Fusion with the identical 3COM  MODEM+ROUTER+FIREWALL+ SWITCH.

Please advice me whether I should be assigning any ports on the 3COM for the SPA to use. or any other alternatives you can suggest to eleminate this VFX line dropping.
