I can't figure out how you guys are getting tf.arctele.com to work. I haven't tried configuring it as a gateway yet since I don't have that need.
I've been trying to use it as both a speed dial (to check specific numbers via Nomorobo) and also as part of a VoIP.ms ring group to run incoming calls through Nomorobo. Neither case works for me the way sip.tollfreeproxy.com used to.
However, tollfree.alcazarnetworks.com works great for me in all instances. So I don't really need arctele but it would be nice to have a reliable backup since it seems like tollfree sites are rapidly diminishing.
Also, toll free calls are working again using Sip Broker at Callcentric but still doesn't seem to be working with VoIP.ms.
I'm using it to fork the nomorobo calls in Voice Service-->SPx-->X_InboundCallRoute:
{(5nnnnnnnnn|6nnnnnnnnn|6nnnnnnnnn):aa},{ph1,sp2(18667326184@tf.arctele.com:5060;ui=$1)}
I did not test whether or not the port 5060 suffix made a difference, but it was listed on arctele's website that way.
