VoIP Weirdness in Irish Republic

[linker3000]

Here's something to mull over:

I have just come back from a trip to the Irish Republic. While over there, I setup my Friend's PC with SJPhone (softphone) as an extension on my UK-based Asterisk server.

Everything works fine but the real kicker is that if I ring their SIP extension (SJPhone), their *HOUSE* phones also ring! The setup is a DECT and a regular desk phone connected to a 2-way line adapter, plugged in to a filter also hosting an ADSL router/wireless AP.

There's no ATAs involved so I can only presume that there's some VoIP-aware kit on the line (Eircom's Centrex system?) that's getting triggered?

Anyone able/care to elaborate or even speculate!?

Ah. Well im guessing it is because if your plugging it into your *RING RNIG* Line it your phone *RING RING* will think ah somthings coming through that *RING RING* line coming out of my back side.

So it will go *RING RING*

Lol :D

Drinking late at night and then forum posting can be real embarrassing, eh!?

embarrassing for him yeah but it gave me a good laugh

Anyway did you ever get this sorted? It's an interesting one. My first stop would be to try a different filter, in case the ADSL signal is interfering with the phone signal. Can think of a few other things, long shots but worth a try.

I setup the software on my last day there so I did not get an opportunity to take things further. My only train of thought is that some SIP-aware kit on the line at the exchange had identified the PC registering and had intercepted the inbound call and triggered a ring tone on the landline too - far fetched but at least consistent with the fact that this was a 100% repeatable event.

I might see if I can get any sense out of Eircom on this.
