I am getting an error when I try to make an intercom call from a softphone to a SNOM 320. I get a “401 Unauthorized” in the siptrace and a “No Matching gateway found” in the log. I can successfully make an intercom call between my softphone and a Polycom 501, so it must be something with the SNOM.

bkw suggested that the problem was in the challenge/response between FreeSWITCH and SNOM. In the SNOM’s Setup/Advanced/Behavior page I have set “Challenge/Response” off, “Enable intercom” on and “Type of Intercom Answering” to “Handsfree”. The error is still “401 Unauthorized”.

What more do I need to do?

Lars,
It looks like FreeSWITCH is sending the challenge to the Snom. Note this line from the debug log:
2009-07-14 08:12:32.333079 [DEBUG] sofia.c:4587 IP 192.168.10.11 Rejected by acl "domains". Falling back to Digest auth.

For testing purposes you can edit acl.conf.xml and add a new line right after:
<node type="allow" domain="$${domain}"/>

Add:
<node type="allow" cidr="192.168.10.11/32"/>

Restart FS or issue this command at the CLI:
reloadacl reloadxml

Then try your call again.

To learn more about how you can have your local users bypass the "domains" acl without editing acl.conf.xml then look in conf/directory/default/brian.xml. At the top of that file you will see a note about how adding a cidr= attribute to your user tag will let you bypass the domains ACL check.

Enjoy!

Thanks, Lars
