I have a small router with Call manager Express on it. I have the system recieving and sending calls from a SIP provider. I also have calls coming in over regular internet to my IP address. Some calls are rejected though. If there is a leading + infront, the Call manager sends a 404 response. If the call comes in without the leading + it works no problem.
I guess my question is how do you get all inbound calls to remove a + if a call comes in with a plus but leave all other calls alone if there is no leading +
