Voice gateway for outbound toll-free calling
mhbrekke:
I have an Obi110 with SP1 configured for voip.ms. SP2 is unused. I am able to place calls through SP1, so there are no problems with SIP registration.
I had previously set up VG1 to forward calls through SP1 to tf.callwithus.com:
Access Number: SP1(tf.callwithus.com)
The setup used to work (confirmed by reviewing my call logs to make sure that the call was connected to SP1).
The gateway doesn't work today. If I try to place a toll free call, I get a (female) voice response indicating that the call could not be connected. The call history shows:
Terminal ID: SP1
Peer Number: 18662037023@tf.callwithus.com
End Call (400 Content-Length mis-match)
If I change tf.callwithus.com to tollfree.alcazarnetworks.com I get:
Terminal ID: SP1
Peer Number: 18662037023@tollfree.alcazarnetworks.com
End Call (400 Bad Request)
Any ideas? Nothing has changed in my network configuration, so I can't explain why this suddenly quit working.

Just guessing, but there might be a parm on SP1 that the tollfree providers don't like. Try using SP2 for your Voice Gateway.
Setup a dummy SIP definition on SP2 like this:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer: 127.0.0.1
Voice Services -> SP2 Service -> AuthUserName: anything
Voice Services -> SP2 Service -> X_RegisterEnable: unchecked
Voice Services -> SP2 Service -> X_ServProvProfile: B
Point the Voice Gateway ay SP2:
Access Number: SP2(tf.callwithus.com)

OK, if I use the "dummy" SP2 then I can connect to SP2(tf.callwithus.com). alcazar still doesn't work (503 Service Unavailable - Route Advance). It's a different error than I was getting yesterday, but still can't complete the call.
I guess I can live with this for now, but it's strange because I had been using SP1(tf.callwithus.com) for a month or so until yesterday. I was hoping to leave SP2 open so that I can add a SIP phone or softphone and route it through the Obi's call processing. I don't know if I'm better off using a hosted PBX for this type of call routing?
I have to use one of the registration-less toll free providers because voip.ms puts a limit on the percentage of toll free calling that I can use and the majority of my VOIP calls are to a teleconference bridge.

I never got Alcazar to work.
These are the tollfree services I use:
tf.arctele.com
tf.callwithus.com
sip.denetron.com
There are others.

You can't register a SIP phone or softphone to an OBi1xx.
You would need an OBi2xx.
If your phones can call out without registration then you can use the SP2 dummy definition with a small modification like this:
This will process outbound calls and route them to SP1:
Voice Services -> SP2 Service -> X_InboundCallRoute:
{OBi110>(1xxxxxxxxxx):sp1},{ph}
This will send inbound calls on SP1 to the softphone:
Voice Services -> SP1 Service -> X_InboundCallRoute:
ph,sp2(anything@xx.xx.xx.xx:5060)
(xx.xx.xx.xx is the IP address of the computer running the softphone)
Phonerlite Softphone on Windows:
Download and install:
http://www.phoner.de/PhonerLiteSetup.exe
When you start Phonerlite I think wizard will popup because no accounts are defined.
Proxy: 192.168.1.100:5061 (IP address and port of OBi110 SP2)
Click right arrow.
User Name: OBi110
Click right arrow.
Change Profile Name: OBi110
Click check mark
Click Server Tab
Uncheck Register
Save
A SIP phone would have a similar setup.

Pretty sure CallWithUs web page says you can make toll free calls using tf.callwithus.com without having an account, but I think I got a message something similar to what you are getting when I tried it. You can open an account for only a few dollars and just use it for toll free. They do not require your device to register to make a call so you should still be able to use a voice gateway. As far as the other post about possibly having some setting in SP1 that CWU doesn't like, I can relate to that also. I experienced a similar issue when I tried to use a voice gateway to make outbound calls through Asterisk. :'(
