Hello All. I'm trying to install 2 Instances of openser on the same
machine with the following interfaces:
Instance #1 -----> 172.16.18.2 and 192.168.1.112
Instance #2 -----> 172.16.1.2 and 192.168.1.113
I made one installation on the default OpenSER folders and one in the
/usr/loca/openser_1/
The configuration went quite smooth. The first instance of the server is
running with no problem at all, but when I try to start the second
instance I got an error that it was unable to resolve the IP addresses I
add the following lines to the /etc/hosts file:
### OpenSER 1st interface configuration ####
192.168.1.112 openser1_internal
172.16.18.2 openser1_external
### OpenSER 1st Interface configuration ####
### OpenSER 2nd Interface configuration ####
192.168.1.113 openser1_internal
172.16.1.2 openser1_external
### OpenSER 2nd Interface configuration ####
After that Now I have the following error:
Jan 5 17:26:30 atel-router ./openser[17772]: ERROR: tcp_init: bind(7,
0x813e194, 16) on 192.168.1.112:5060 : Address already in use
Any Help will be appreciated, of better is there a How-to on OpenSER
multiple instances please let me know.
Thanks in advance
Gerardo Amaya

Does anybody have a way to force an unconditional branch to a failure route.
Or, if not that, a command that will surely fail and force a branch to
the failure route.

Hello all,
We are currently performing a number of interoperability tests between
OpenSER and SIP Communicator over IPv6.
The good news is that we have successfully established IPv6 calls
between two SIP Communicator instances registered on our local OpenSER
installation (version 1.1.0-7 on Debian testing).
There is however something weird we'd appreciate any ideas on what might
be causing it:
When running OpenSER with a default configuration, any ACKs that the
caller tries to proxy through OpenSER don't get forwarded to the callee.
Changing syn_branch to "no" (we saw somewhere that this might be
related) didn't have any effect. I am attaching a log snippet that seems
to be corresponding to the ACK processing.
In a desperate attempt to resolve the issue we added the following to
our route{} clause:
if (method == "ACK")
{
forward("[2001:660:4701:f009:213:ceff:fea7:a88c]:5060");
exit;
}
where [2001:660:4701:f009:213:ceff:fea7:a88c] is the IPv6 address of the
callee.
This worked but it is obviously not (even close to) a "viable" solution.
So our question is, what would be the best way to make OpenSER forward
ACKs that a caller is trying to send to a callee?
Thanks
Emil

Hello All. After investigating quite a while about this issue I'm kind
of desperate now, I will appreciate your help on this.
I have a OpenSER Server with multiple interfaces, I'm able to handle all
the SIP packets with the multi homed enabled. Now the part that I'm
having real trouble with is the RTP audio streams. After struggling with
MediaProxy I finally started using RTPProxy for this, since it has
bridge mode available. Now the problem is that I have more than one
network to connect audio from, so the internal and external
configuration is not enough for me. So my questions are:
1.-Can I have RTPProxy Bridge mode working for all the interfaces in my
server?
2.-Can I have more than one RTPProxy socket available for each of the
multiple interfaces I'm connecting in order to have the audio working,
so each route will use the proxy of their own network?
3.-If #2 is true, is this where the force_socket and force_rtp_proxy
functions play a role in my configuration?
Please help!!
Thanks you so much in advance

bingo. you are right. you have to configure openserctl to use the proper
username/password.
take a look at /etc/openser/openserctlrc

Hi Davor
I notice you had a problem with one way audio. I have the same problem but
when the X-Lite client is behind firewall. Do you have any ideas or
direction I could follow?
Best regards
Gareth

Hello all,
I have SER 0.9.6 installed, along with Mediaproxy 1.8.0, Nathelper, SEMS
0.9.6, SerWeb 0.9.6 set up as a PSTN gateway on CentOS. However, there
are some issues with NAT, Accounting (ACC) and the way I setup the web
access. Also, I'd like to get to Voice mail and Conference working.
Basically, I'd want you to take what's there and finish the install so
everything works together. For an expert, all this is probably a few
hours job. There is already SSH access in to the system.
I started with a "LiveCD - VOIP" version of SER
(http://www.wifi.com.ar/english/voip.html) with all the above (almost)
but found it grossly out-dated and the Author unwilling to assist nor
update to current releases. FYI: If you are are thinking of purchasing
this software, save you money! The only thing nice is there is a
prepaid billing script that might be converted to current releases.
I just need to 'jump-start' this project to some usable level. I'm
willing to pay for your time.
If you are interested, please contact me at bart (at) icpage (dot) com.
TIA
Bart
Hi all,
SER 0.9.6 is used as registrar/proxy and asterisk 1.4 as media
server (voicemail, ...)
The situation when phone A calls phone B and B is busy is handled by
a failure route
revert_uri();
rewritehostport("10.11.12.13:5070");
append_branch();
t_relay;
This works fine, if for example phone A is some Snom 190.
If another asterisk server is used instead of phone A it works if
"pedantic=no" is set in the sip.conf of asterisk.
If it is "pedantic=yes", then asterisk compares the tags in the To
header fields. There is one tag from phone B and a second from the
asterisk media server. Asterisk ignores every response not having
the tag used by phone B.
IMHO asterisk is wrong, but since I can't controll which asterisk
servers are used as clients - is there a way to may asterisk happy?
Would it be possible to remove tags from 1XX responses?
