I'm having a heck of a time getting incoming calls to appear on my CME 4.0.3 (12.4.15T8 on 2650XM). Outbound dialing works with the dial-peers I have and have configured sip-ua (to what I think it should be) and I am getting a SIP 400 (invalid host) coming back.
My CME is behind a Linux NAT router and wondering if this is a possibilty (but registration with outside SIP gateway works as does outbound dialing?).
Here's the message I get: SIP/2.0 400 Bad Request - 'Invalid Host'
Here's my sip-ua portion of the config:
authentication username 1204XXXXXXX password 7 <SNIP>
nat symmetric role passive
nat symmetric check-media-src
calling-info pstn-to-sip from name set <My Name>
retry invite 2
retry register 10
timers connect 100
registrar dns:sip.ca1.link2voip.com expires 120
I've tried the settings with and without the nat commands to no avail. Thanks for any help!
