RTPEngine control protocol via TCP
by Alex Balashov 04 Mar '21

04 Mar '21

Hi, Recent versions of RTPEngine (9.x+) implemented support for speaking the "NG" wire protocol over TCP, via the `--listen-tcp-ng` option. Does the Kamailio `rtpengine` module support this, and/or are there any plans to? We've run into a few scenarios where very large responses from RTPEngine can't make it back to Kamailio over the UDP protocol due to fragmentation problems in unique network settings like tunnels. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

topos event_route question
by Juha Heinanen 03 Mar '21

03 Mar '21

I tried to skip topos stripping based on R-URI hostpart like this: event_route[topos:msg-outgoing] { xinfo("******** at topos:msg-outgoing with $rd\n"); if ($rd == "example.com") drop; } and got this to syslog: Mar 2 18:35:59 lab /usr/bin/sip-proxy[22441]: INFO: <script>: ******** at topos:msg-outgoing with kamailio.org Where does $rd == kamailio.org come from, since R-URI hostpart of the request does not have that domain? Or is it so that $rd cannot be used in that event route? -- Juha

TOPOS (5.5) answers '404 Not Here' when b side send BYE
by 张阳 03 Mar '21

Dear Daniel: When I was using the topos module, I found that if a bye message was sent from side B, kamailio would return a 404 message. When I remove the topos module, the call is normal, attached is sip pcap. 172.18.67.50:5060 and 172.18.67.40:55066 Are different ports monitored by the same kamailio Looking forward to your reply!

Hunt groups with alias_db_lookup
by Adam McCarthy 02 Mar '21

02 Mar '21

Hello, I'm currently using alias_db_lookup to map inbound calls from my SIP carrier to internal endpoints e.g., 1NXXXXXXXXX(a)sip.example.com -> alice(a)sip.example.com. This works well, but I would now like to simultaneously call alice@ and bob@, e.g. alias_db_lookup(...) # somehow return alice@ and bob@ append_branch("sip:bob@sip.example.com") as described here: http://kamailio.org/docs/modules/devel/modules/tm.html#tm.serial_forking This is effectively a hunt group, where two users are called and once one user picks up the call, the second is sent a CANCEL. How would I acheive this with Kamailio? Thanks, Adam

Load htable from MongoDB
by Sergiu Pojoga 02 Mar '21

02 Mar '21

Hi there, Question: is it possible to load a htable, defined by columns, from a MongoDB collection, when a certain "column" is an object with multiple elements? For example: modparam("htable", "htable", "users=>size=10;dbtable=users;cols='FirstName,LastName,Location:Prefix';") Fails when trying to load the value of Location.Prefix { "FirstName": "John", "LastName": "Doe", "Language" : "en", "Location" : { "Country" : "USA", "City" : "New York", "Prefix" : "+1" } } Thanks in advance.

Need help in transforming an SDP string through a re.subst
by Denys Pozniak 02 Mar '21

02 Mar '21

Hello! There is a task to remove a fragment (*a=rtpmap:8 PCMA/8000#015#012*) from the SDP string generated by the rtpengine. *v=0#015#012o=kw 1614043485 1614043486 IN IP4 185.19.237.77#015#012s=kw#015#012c=IN IP4 1.1.1.1#015#012t=0 0#015#012m=audio 31828 RTP/AVP 0 8 101#015#012a=silenceSupp:off - - - -#015#012a=direction:both#015#012a=rtpmap:0 PCMU/8000#015#012a=rtpmap:8 PCMA/8000#015#012a=rtpmap:101 telephone-event/8000#015#012a=fmtp:101 0-16#015#012a=sendrecv#015#012a=rtcp:31829#015#012a=ptime:20#015#012* The most logical option seems to be using the re.subst transformation, but so far no success. $avp(write_sdp_pv) = $(avp(write_sdp_pv){re.subst,/a=rtpmap:8 PCMA\/8000%23015%23012//s}); Сan there be an alternative or am I doing something wrong with the re.subst? -- BR, Denys Pozniak

(changing list to sr-users) Hello, Do you see an iptables rule belonging to the rtpengine module? If you do a test call, are the packet counters increased on this iptables rule?
