I have an IP500 V1 with release 6.0.18, and have 2 incoming sip numbers. The first one is working fine but the second one which was recently ported does not reach the pbx. Monitor traces show that the second number has a + inserted at the front of the number string. When I inserted the +, I get the same problem. I tried both settings in the Call Routing Method : Request URI and To Header with no success. Thanks in advance.
