I signed up for Viatalk after 4 years with Packet8.  I was a big fan of Packet8 and was very hesitant to leave.  I was looking for a provider that would support Asterisk.  There are several residential providers that support BYOD, but none are as good of a deal as Viatalk.  Here are a few settings you may want when you setup Viatalk and Asterisk:

• DTMF type:  Currently Viatalk uses Inband for DTMF type.  I had no problems setting up outbound calls to use Inband for DTMF, but I couldn’t get dialing into my asterisk box to detect DTMF tones.  I put in a trouble ticket with Viatalk and asked to be changed to RFC2833.  24 hours later they made the change and it works great.

• Inbound delay when answering the phone.  If you search the Viatalk forum on DSLreports you will find that many people complain about a 3 second delay when answering the phone.  Here is what I setup in freepbx to fix that:

[custom-via-did]  //add this in extensions_custom.conf

exten => 1,1,answer
exten => 1,n,wait(1)
exten => 1,n,Goto(ext-local,110,1) ;ext 110 is my extension

Then in freepbx send the incoming call to Custom App: custom-via-did,1,1

The disadvantage to this is you actually answer the call before a human answers it.
