[OpenSIPS-Users] ASR & ACR per country/destination

[Abdoul Osséni]

Hello dear list,

I am looking for a tool that will provide me call statistics (ASR and ACD)
by destination/country with alerting by emails.
I try to detect when a sip provider does not work well in order to route
the traffic to another sip provider.

Thank you.

[OpenSIPS-Users] HEP mi_datagram tracing

[Ben Newlin]

Hi,

I’m running into an issue in 2.3.3 with HEP tracing and the proto_tcp and 
mi_datagram modules. I am not setting the trace_destination parameter in the 
mi_datagram module, so I expect tracing should be disabled. I am setting the 
parameter in the proto_tcp module, but the trace_on parameter is disabled. 
However, tracing still seems to be attempting and is causing errors.

This config:

#// Even though we are not receiving HEP,
#// this listener is required by OpenSIPS
#// to use the proto_hep module.
listen=hep_udp:PRIVATE_ADDRESS:9060
listen=hep_tcp:PRIVATE_ADDRESS:9060

#// DATAGRAM Management Interface
loadmodule "mi_datagram.so"
modparam("mi_datagram", "unix_socket_mode", 0666)
modparam("mi_datagram", "socket_name", "/tmp/opensips.sock")
modparam("mi_datagram", "children_count", 1)

#// PROTOcol HEP module
loadmodule "proto_hep.so"
modparam("proto_hep", "hep_id", "[hep_tcp] 127.0.0.1:9060; transport=tcp; 
version=3")
modparam("proto_hep", "hep_capture_id", 1)
modparam("proto_hep", "homer5_on", 1)

#// PROTOcol TCP module
loadmodule "proto_tcp.so"
modparam("proto_tcp", "trace_destination", "hep_tcp")
modparam("proto_tcp", "trace_on", 0)

Generates these errors:

Mar 30 13:52:25 [328] ERROR:proto_hep:build_hep3_buf: unknown IP family
Mar 30 13:52:25 [328] ERROR:proto_hep:send_hep_message: failed to build hep

Mar 30 13:52:25 [328] ERROR:mi_datagram:mi_trace_reply: failed to trace mi 
command reply!

Tracing for the mi_datagram module should not be enabled, but appears to be 
attempting to trace anyway. If I change the HEP config to use version 2 then 
the errors change:

#// Even though we are not receiving HEP,
#// this listener is required by OpenSIPS
#// to use the proto_hep module.
listen=hep_udp:PRIVATE_ADDRESS:9060

#// DATAGRAM Management Interface
loadmodule "mi_datagram.so"
modparam("mi_datagram", "unix_socket_mode", 0666)
modparam("mi_datagram", "socket_name", "/tmp/opensips.sock")
modparam("mi_datagram", "children_count", 1)

#// PROTOcol HEP module
loadmodule "proto_hep.so"
modparam("proto_hep", "hep_id", "[hep_udp] 127.0.0.1:9060; transport=udp; 
version=2")
modparam("proto_hep", "hep_capture_id", 1)
modparam("proto_hep", "homer5_on", 1)

#// PROTOcol TCP module
loadmodule "proto_tcp.so"
modparam("proto_tcp", "trace_destination", "hep_udp")
modparam("proto_tcp", "trace_on", 0)

Generates these errors:

Mar 30 14:33:12 [341] ERROR:proto_hep:unpack_hepv12: unsupported family [1]
Mar 30 14:33:12 [340] ERROR:proto_hep:unpack_hepv12: unsupported family [1]
Mar 30 14:33:12 [341] ERROR:proto_hep:update_recv_info: invalid hep version!
Mar 30 14:33:12 [340] ERROR:proto_hep:update_recv_info: invalid hep version!
Mar 30 14:33:12 [340] ERROR:proto_hep:hep_udp_read_req: failed to run hep 
callbacks
Mar 30 14:33:12 [341] ERROR:proto_hep:hep_udp_read_req: failed to run hep 
callbacks

If I remove the trace_destination parameter from the proto_tcp module all 
errors stop. Interestingly, if I set the HEP listener port to something 
different than the destination port, the errors also stop.

Thanks,
Ben Newlin

Re: [OpenSIPS-Users] HEP Address Hostname error

[Ben Newlin]

Has anyone had a chance to look into this DNS issue?

Subject: HEP Address Hostname error

Hi,

While upgrading from 1.11 to 2.3, we have run into an issue with the parsing of 
the hep_id parameter in the proto_hep module.

In 1.11, we used the duplicate_uri setting in the siptrace module like so:

modparam("siptrace", "duplicate_uri", "sip:homer-hep.test.com:5656")

In 2.3, we converted this into the appropriate module config for proto_hep:

modparam("proto_hep", "hep_id", 
"[hid]homer-hep.test.com:5656;transport=udp;version=2")

However, this results in OpenSIPS complaining about receiving the wrong address:

Mar 26 19:59:58 [332] CRITICAL:core:mk_proxy: could not resolve hostname: 
"homer"
Mar 26 19:59:58 [332] ERROR:proto_hep:send_hep_message: bad hep host name!
Mar 26 19:59:58 [332] ERROR:siptrace:send_trace_proto_duplicate: failed to 
forward message to destination!
Mar 26 19:59:58 [332] ERROR:siptrace:save_siptrace: Failed to duplicate with 
hep to 

It appears the proto_hep module parameter parsing doesn’t allow for 
dashes/hyphens in the address portion, so it ends up with only a small part of 
the actual hostname of our Homer server.

Thanks,
Ben Newlin

Re: [OpenSIPS-Users] How to extract SIP-I ISUP 'Redirecting number' parameter

[Vlad Patrascu]

Hi,

I've pushed the fix, but bear in mind that you could still extract the 
redirecting number without full subfield access support. By just reading 
from "$isup_param(Redirecting number)" you get, as a string, the full 
ISUP parameter value in hex representation. From that, knowing the 
parameter format from the ISUP specification, you could parse the number 
yourself in the OpenSIPS script.

Btw, is it possible to extract ISUP part as is in binary form and read
by some external script? Can anybody advice me any library to parse
ISUP binary data?

Thank you!

I submitted https://github.com/OpenSIPS/opensips/issues/1323 - maybe
your patch can be applied?

2018-03-29 10:53 GMT+03:00 Arto Kuiri :

Hello,

I had same problem and made my own patch. See attached diff, it adds support 
for:
- redirection info (reason in same format as in SIP diversion header, commented 
ITU Q.763 version)
- original called number
- redirection number

Meant to make feature request/patch, but somehow forgot it.

Best regards,
Arto Kuiri

Hi,

Unfortunately "Redirecting Number" is not currently supported, but you
could open up a feature request regarding this, as it would be not very
difficult to implement.

extract it? 'Redirecting number' parameter value is visible in
Wireshark now as ISUP parameter with t=11 and l=7
