SIP Error Response = 503 Service Unavailable 2

[Bonker1974]

Hi All,
I have a issue, I have an IP Office 9.0 connected via SIP to Session Manager. When I make a call from CM to the IP Office i get the below error Response = 503 Service Unavailable.

The the trunks on the IP Office is configure as SMLine.


2/13/15 2:07:54 PM-005ms Line = 9, Channel = 1, SIP Message = Response, Direction = From Switch, From = +6121@combank.cb, To = 5010@mydomain.com, Response = 503 Service Unavailable
2/13/15 2:07:54 PM-008ms Line = 9, Channel = 1, SIP Message = Ack, Direction = To Switch, From = +6121@mydomain.com, To = 5010@mydomain.com

I'm wondering if there is a mismatch between the IPO and the SM i.e. IPO is sending SIP and the SM is expecting SIPS.

Wireshark, IPO trace or something extra would be good

Take Care

My wish has come true. I no longer know how to use my telephone.
