Hello.
I was just curious how SER handles calls with its own
members.
For example: I want to have around 10 users on my SER.
If one calls the other, does the bandwidth get
channeled through my server, or is the call handed
off, directly connecting the users and saving my
bandwidth?

yes, you can rewrite contact and sdp if the UA sends out internal IP

some folks have asked domain_suffix as a parameter to enum_query. i
just committed some changes for that purpose.
the syntax now is (from README):
1.4.1. enum_query(), enum_query("suffix"), enum_query("suffix", "service")
Replaces the current Request-URI with the result of a successful enum
query on the user part of the current Request-URI, which is assumed
to be of the form +up-to-15-decimal-digits. An NAPTR record whose
flags field has string value "u" and whose services field has string
value "e2u+service:sip" or "e2u+sip" (if "service" parameter is not
given) is looked for. Returns -1 if enum_query fails and 1 otherwise.
If "suffix" parameter is not given, value of domain_suffix module
paremeter is used.
Example 1-2. enum_query usage
...
enum_query("e164.foo.com.");
...
i did some testing on the first two versions of the call and it seemed
to work. i didn't test the last version.
this is in unstable. let me know if you find problems.

Greg,
You can test with Managed DNS if you wish.

looks like some process is already listening on port 5060, therefore ser
can't bind to port 5060!

Can someone share a complete bind setup example for
enum support. I've been stabbing (unsuccessfully) all day.
I'm pretty good with DNS, just can't grasp the NAPTR thing.
---greg
You have to configure the DNS server to reverse resolve your IP address
to the name of your PC (DemoSIP ?).
You could also to this by adding the domain name to your /etc/hosts
file.

Can you please re-submit the patch against original sources, because it
is really easier to work with the patch than with modified sources.
Thanks!

This is useful if you have two different service providers (SER1 and SER2) both providing nathelper/rtpproxy support to their registered clients. No change to the ser.cfg is required. (For the curious - how this works is - when force_rtp_proxy is called, before the media IP:port is replaced by that of the rtpproxy, a check is made if the original IP address is a private address - if yes, nathelper tells rtporoxy to wait for atleast one UDP packet from this end. But if the IP address is a globally routable one, nathelper passes this IP:port to rtpproxy)

Hello,
I just installed SER today and I'm having some
trouble. When I check /var/log/messages, I see the
following:
Dec 16 12:39:16 DemoSIP ser: WARNING: could not rev.
resolve X.X.X.X
Why can't ser resolve my IP address? How do I fix
this problem?
Thank you for your time

Hi,
I am able to register with iptel.org. Is there any test numbers to confirm
whether my sip-phone works / not..?
my id is <sip: san(a)iptel.org <mailto:san@iptel.org> > and my peers id is
<sip:dheeraj@iptel.org>
If both the phones are behind NAT, How to send SDP messages from UAC to
UAS..?
Thankyou.
Kind Regards,
Santhosh.S
