I've been testing my OBi110 setup with a Verizon / Pantech UML290 4G modem in a Cradlepoint MBR95 4G router.
Late last week a Verizon firmware upgrade kept my laptop from accessing the internet, and after a replacement modem showed the same problem they sent me a Verizon USB551L modem. That fixed my laptop getting on the internet but has caused a very strange problem with the OBi110.
Anytime I try to make a toll free call (early media or not), I get a message saying "The number you dialed 1800-xxx-xxxx was rejected by the service provider. Reason 500" All other calls are fine.
If I plug in the ethernet cable from my WISP service I get no problems, but I also wasn't getting this issue with Verizon's Pantech UML290 modem either. (I do have to manually set port 5080 or SP2 CallCentric doesn't register though). I'm connecting to the same Verizon service, any ideas why this is happening?
SP1=GV, SP2=CallCentric (911), VG8=ideasip (all Toll Free)
