Can't make calls through voip.sapo.pt with voxalot
 

I am trying to establish calls using my VoIP service provider. This is the configuration I would use on a Linksys SPA-1001:

Proxy: voip.sapo.pt
Use Outbound Proxy: yes
Outbound Proxy: proxy.voip.sapo.pt:5070

The user ID is of the type: +35130xxxxxxx

It works on my ATA. But it doesn't work through voxalot. VoipBuster however works on both.

Thanks.
