Re: [sipx-users] SIP trunk between Cisco Callmanager 6 and SIPXECS
The basic logic is that when the proxy receives the INVITE from
Callmanager, it believes that the From URI is identifying a user on the
sipXecs system. In order to get that user to present credentials, it
returns a 407 response. Apparently Callmanager does not have
credentials for the realm, so it abandons the call.
There are a number of ways of attacking the problem. To start off with,
is the caller really a member of the domain? The From URI is
<sip:6005@xxxxxxxxxxxxx>, is that really a correct identification of the
caller? It is possible that the user is better identified as part of
some other domain, and Callmanager should be reconfigured to put a
different domain in the URI.
A second question is whether user 6005 has sipXecs credentials. If 6005
exists *only* on the Callmanager side, just deleting 6005 from the list
of defined users in sipXecs will eliminate the 407.
You could also look into providing Callmanager with SIP credentials. I
expect that there is some way to configure that.
