Hi All,
I'm new to all this stuff, so apologize if these are dumb questions.
I have an account with a local/ld voip provider. They provide me a SIP
connection to/from the pstn. I have this working with sjphone and xten.
I also have ser running (very basically) and handling/routing calls for
local softphones registering with it.
I really want to be able to receive incoming pstn calls and route them
internally.
Here's where my ignorance comes in. The sjphone and xten register at the
vendors registrar as sip:nnnn@vendor.com. I havn't seen an example or
read anything how I could configure ser to do that.
Also, the SIP line is authenticated. How do I tell ser to use a set of
credentials when sending/receiving SIP messages to my vendor?
Thanks!
Tim
i wanna find more information about SOP (SIP Operator Pack (SOP)): Application
Agent, but don't find nothing i send email to info(a)iptel.org but no receive
response.

thks a lot

Hi,
Is it possible to configure SER to forward calls that are busy only for subscribers that have ordered the service?
I can't see that subscriber's forwarding information is stored in the database.
Also does SER support privacy standards: RFC 3323, RFC 3325?
Regards

Hello,
I'm running ser 0.8.14 on Debian Sarge installed from debian packages
found on the ser site. I can register fine with the proxy, but when
trying to place a call I get "Too many Hops" errors. Disabling the hops
check the calls loop.
You can find my ser.cfg below.
Any help would be greatly appreciated.
thanks
Luca

Hi,
Hope someone can help me. I have a fairly bad NAT situation.
Clients are behind NAT and SER is behind NAT. The idea is that the
clients will register to the public address which is assigned to my
router and I have enable port-forwarding to send the packets onto the
pc running SER listening on 5060. This situation worked when clients
registered with Asterisk but I would rather them to register with SER
and just use Asterisk for voicemail etc.
My config is like the default except the nathelper and mysql modules
are loaded. I have looked at the following websites but all the
configs are very different and use different rtp proxys..I am also
confused as to how much configuration is required to accommodate nat
http://lists.cs.columbia.edu/pipermail/sip-implementors/2004-February/
006179.html
http://voip-info.org/wiki-SER+example+NAThelper
Could someone give me an idea of how the script should be modified,
what else must be installed (rtp proxy wise)or any ideas as to why my
clients cant register?....Im presuming its nat...
Thanks a million,
Aisling.

Hi,
How many simultaneous calls the SER is enabled to do?
What are the hardware specifications?
What is the more stable version of SER to this case?
Thanks a lot.

Hi All
I am using SER from last one year and found it really interesting and easy
to use. I have one query now. Can we port SER on some embedded system also.
Can anyone guide me for that.
Regards
