Re: [sipx-users] SIP trunk between Cisco Callmanager 6 and SIPXECS

["Sen Heng" <hengs@xxxxxx>]

I just built a latest Sipx 4.1 trunking with Cisco CM 6 and 7. Both of them
working fine. Sipx can call CCM, CCM can call sipx.

Thanks,
Sen

Subject: 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.
