[Gllug] Is this a silly idea - VOIP telephony with Asterisk?

Hello John,

I am similarly afflicted. I have a Desktop phone registered with
SIPGate connecting on port UDP 5060. This works fine without any
modification on my ADSL router.

I recently bought a wireless handset and I'm trying to connect it to
the same account. I asked SIPGate for help and they instructed me to
change the ports on the second handset to connect to 5062 (This may be
different for your provider)

So far it doesn't work but I am still playing with it.

I have this in mind as well - although I'd rather just hang both of my
handsets off of the SIPGate service. If I go for an Asterisk server I
plan on using Asterisk at Home which has some very nice web-based admin
tools thrown in as well as reporting etc

It is very feasible - and I think you are spot on, on both counts

Thanks
