Hi,

I have installed asterisk 1.8.11.0. but there’s a problem with the sip
channel module.

The module chan_sip.so exists in /usr/lib/asterisk/modules, but it
won’t load at startup.
CLI command module load chan_sip.so also did not work.

Hello List!

My Asterisk stopped making SIP-calls today, I could call from external, and
saw Call coming in over PRI, but calling the SIP/Device
wont work. I saw 5 open channels – all chan_spy. Only a restart helped.

In the messages-file i found from yesterday:

I’m not sure what’s going wrong? My ulimit should by unlimited.

I’d appreciate some more details. Is it related to dahdi_cfg? pciradio
(is it still used?) ?

Bug reports would be welcomed.

I’m attempting to pull SIP users from LDAP, following the instructions from here:

http://asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/ExternalServices_id291590.html

However, when I attempt to register a user from LDAP, I see on the console:

chan_sip.c:24431 handle_request_register: Registration from ‘‘ failed for ’172.20.24.131:3072′ – No matching peer found

Poking around with tcpdump I see that Asterisk sends a query to the LDAP server, and gets a response for that user, so the connection is working at least. So, Asterisk must not be recognizing the record as valid. However, I have no idea why. Is there some more verbose logging that can be enabled? How can I do test lookups with the realtime engine? I can’t find any place to start troubleshooting this issue.

I’m full of other questions, like:

what’s the difference between “sipusers” and “sippeers” in extconfig.conf?

what happens if I don’t provide all of the attributes (amaflags, callgroup, callerid…there are dozens listen in res_ldap.conf) in my LDAP directory? I don’t really want to duplicate all those settings for each user in my organization: that’s not very managable.

Any guidance from someone who’s been down this road would be appreciated.

Hi,

I’ve read here and there how Asterisk could send SMS but I didn’t find
much about how to receive SMS and forward them to an email box.

1. First of all, I don’t think my telco would let me receive any SMS
my landline.

2. Maybe I could find providers selling this service for a monthly fee;

3. I could build and operate my own infrastructure.

Given this asterisk-users mailing-list purpose, and for curiosity’s
sake, how could I build my own SMS reception service with Asterisk
(1.6.1 or later) ?
Which channel (chan_mobile, chan_datacard, …) and hardware would be
appropriate ?
Suggestions ?

Regards
