I've got nathelper module and rtp proxy running. When I start up SER, the
natmodule detects rtpproxy running so it enables the support for it.
Something's not running right because I cannot establish a voice
conversation between two user agents. I can, however, establish a connection
between the two user agents. I included my ser.cfg file in a previous
posting and can resend it to anyone who's interested in looking at it.
Any help in trying to configure nathelper and rtpproxy properly would be
greatly appreciated.
Thanks in advance.
Hi All,
I want to generate INVITE request when called party
disconnects a call.
How do we generate requests in SER?
Requirement is - I don't want the called party to
disconnect the call.
Any suggestions most welcome.
Regards,
Suvendu.

Hi!
I am from India, we have a SIP server in USA which use to register on
prefixes of 4 digit like if you want to call a no. 12127773456 then the sip
message will look like 524112127773456(a)202.66.135.55, where 5241 is the 4
digit prefix for authentication. Now I want to have a SIP proxy server at
our end it self and it will redirect the uri to the destination gateway.
How to do that? Any body have the configuration file for this configuration?
Thanks

Hello,
- I have a group : "TEST"
- In this group, i have a lot of phone's numbers.
Only my group "TEST" is REGISTERED on SER.
How can i redirect INVITE requests who arrive on SER to this phone's
numbers, to the IP@ of the group "TEST".
I have configured that, for this moment :
if (is_user_in("To","TEST")){
forward("62.38.29.6", 5060);
break;
};
HOW CAN I FIND THE IP@ OF THE GROUP "TEST" REGISTERED ???
Thanks a lot for your help.
Best Regards
Nicolas RUIZ
Here's what my ser.cfg file looks like. I'm still unable to get a voice
conversation going using xlite. I can establish a connection between two
xlite ua, but seems like my rtp packets are blocked somewhere. I have
rtpproxy installed and running. When I run SER it sees rtpproxy running and
enables support for it. I'm running SER in debug mode so I can see the
messages.
Is there something I'm missing or doing wrong in my ser.cfg file?
By the way, I'm running this on Redhat.
Thanks.

Hi
get rtpproxy from CVS and set it up and it will work.
I'm doing the same way you are right now
a couple of days ago I post a message on the list
with the CVS command to download rtpproxy and the
URL of SER config to use it with nathelper
Hope this helps

Hi,
I'm testing a snom 190 behind nat, using an external stun server.
Problem is that the phone first register itself with the internal ip
address, then checks for stun and registers again with the correct ip
address.
After the registration timeout the phone register just once with the
correct ip .... any idea about such behaviour ?
Tnx !
P.S.
Fw version is snom190-SIP 3.46

Hi
How can I configure SER as a SIP Proxy server without any authentication. My ser is loaded on to linux with mysql.
