Have new spark VDSL2 connection working at my parents place. That part is great. Spark HG630b modem with ethernet cable into WXC MP264 router. 

They have a world exchange MP264 router that provides them with a VOIP phone connectivity. Their old connection was a local wireless dish on the roof connected to MP264 via WAN ethernet cable. 

Even though all front LED lights on MP264 are green, can't receive incoming calls and very slow to dial out if at all.

So after talking to WXC support, he suggested I use the MP264 for the VDSL connection. Tried setting this up as per WXC support page and spark other modem settings. Rebooted. Powered off etc. Didn't seem to work and oddly enough, dsl light on the back wasn't lit up. Support wasn't that helpful / interested. He suggested I port the VOIP number to spark or switch VDSL2 to wxc.

Also factory reset MP264 router as I forgot the password. Confirmed all working correctly with old wireless lan cable. (still active). Also note cable not left in when trying to setup VDSL connection.

My questions are:

 

1. Can the WXC MP264 router work with other ISP providers? i.e. Is it locked to WXC only adsl/vdsl/fibre?
2. If not, can the spark HG630B router be configured to work with VOIP?

    

    

   1. On Advanced - NAT - I tried enabling SIP ALG which showed the default VOIP port. Didn't work.
   2. Is it a simple case of adding port forwarding for the VOIP port?

    

Thanks

Regards
