Description

« Hide

If the Outbound Proxy' field on the 'Phone | Line | SIP' screen is not empty (and is not defined in any containing phone groups) then sipx automatically sets Oubound Proxy equal to the sipx server's FQDN (eg hostname.domain.com) in the generated config file. This is fine for standalone sipx servers. However, on an HA system that's not the appropriate value. The outbound proxy (if defined at all) should be domain.com. Unfortunately, the admin can't just leave the field empty, since the default behavior of sipxconfig is to define it anyway.

The best solution would be for sipx not to populate that field by default with any value at all. If the admin wants to use that config param they can then configure it explicitly on the phone or in a phone group.

Here's a snippet showing the generated config param:

[root@sipxchange ~]# cd /var/sipxdata/configserver/phone/profile/docroot/
[root@sipxchange docroot]# grep -i outbound *
000413230A09.htm:user_outbound1: sipxchange.pingtel.com

In case anyone needs this for a customer or for testing, here's a patch from Douglas which will remove the outbound proxy setting from the GUI entirely:

edit
/etc/sipxpbx/snom/lines.xml
Comment out xml element starting on line number : 119 so original
    <setting name="user_outbound">
      <label>Outbound Proxy</label>
      <type>
        <string/>
      </type>
      <value/>
    </setting >
now looks like
    

I assume that this will be addressed in a better way in a future release. -m

XCF-1680 - Use domain name for outbound proxy instead of FQDN, only matters in HA systems. Still would like to know if the setting is required at all but awaiting test results.

May be better to just leave it blank (though if not, we should definitely set it = to the SIP domain). I don't think we set the outbound proxy by default on other phones types (eg polycom) so why set it for snom?

Asked for info from snom support. When/if I know more I'll update this ticket.

Michael, see ~~XPB-398~~ for answer regaurding setting the value. If AA transfers works, then we cna stop setting the value.

Interesting thread, thanks for the pointer. The difference between the testing done for ~~XPB-398~~ is that they weren't doing HA, so 1) the SIP domain was different, and 2) there was only an SRV record for one proxy (instead of SRV records pointing to 2 proxies, in the case of HA). I think the snoms may have a problem with the latter. Waiting for feedback from snom tech support.

Mike: I am assigning this to you since you said you are waiting for response from Snom.
I think that the original issue is fixed now but I'd like to keep it open to see if we can remove setting outband proxy by default.
