[OpenSER-Users] The best way to allow just a few destinations based on prefix?
by Iñaki Baz Castillo 20 Feb '08

20 Feb '08

Hi, which would be the more ellegant way to allow users to call just a few destinations (based on prefix)? Of course I could do it simply by creating a custom table: "allowed_destinations" with columns: [int_prefix] [description] 34 Spain 44 England ... and latter extract the international prefix from the E164 converted RURI and do a SQL query. But I'd like to avoid using avp_db_query() function. I've reading about PDT, LCR and CarrierRoute modules but they seems to be supposed to other aims. The most similar could be PDT but it needs to strip my prefix XD What do you suggest? should I implement my custom method for this? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[Serusers] Parallel Hunt groups?
by Jeremy A 20 Feb '08

20 Feb '08

Hello, I have an application that requires an incoming call to ring multiple phones simultaneously until one answers or it times out. After that I need to direct the call to another phone or group. Is this feasible using SER? If so, are there any example configurations I can use as a basis - I have already seen the sequential 'hunt group' example, but I need a parallel ring option. Thanks Jeremy

Re: [OpenSER-Users] Cpl Outgoing and Incoming

IMHO the only solution is to send outbound the INVITE (so it comes again to OpenSer by DNS resolution). Something as: if ($si != "IP_OPENSER") { cpl_run_script("outgoing","force_stateful"); t_relay(); # Send out the INVITE. } lookup("location"); cpl_run_script("incoming","force_stateful"); A calls B, the INVITE arrives to the proxy from an IP different than the proxy IP, so the outgoing CPL is runned and the CPL by itself will send out the INVITE. The INVITE will come back to the proxy since B is a local user, but in this case the $si is the proxy IP so the lookup and incoming CPL will be runned. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] Cpl Outgoing and Incoming
by Daniel 20 Feb '08

20 Feb '08

Hi all, I'd like to use either cpl Outgoing (of the caller) and cpl incoming script (of the callee). I mean, if "A" wanted to call "B", and "A" and "B" have CPL script saved on proxy, then the message sent by "A" have to go through CPL-OUTGOING of "A" and then through CPL-INCOMING of "B". How can I get this behaviuor in openser.cfg ? Thanks, Daniel -- Daniel Grotti ________________________ e-mail : d.grotti(a)gmail.com

[OpenSER-Users] Is there OPTIONS keepalive in TCP?
by Iñaki Baz Castillo 20 Feb '08

20 Feb '08

Hi, I register a X-Lite (TCP client) and a Twinkle (UDP client) behind NAT. I dissable STUN, ICE, keepalive, "discover external address", etc... in both. They send a REGISTER to my OpenSer with public IP so I enable OPTIONS pinging ifor both (I confirm that "location" table has the same cflags for the you entries and so, all is correct. But I just see a periodical SIP OPTIONS by UDP for Twinkle. Are they exist in case of TCP? -- Iñaki Baz Castillo

[Serusers] Strict routing problem
by Rosa De Santis 19 Feb '08

19 Feb '08

Hi List. Please, I need some help with strict routing problem. Incoming calls are canceled at 30 secs from an origination provider. The problem seems to be a bad ACK sent from the origination, because it performs strict routing instead of loose routing. The ACK goes from originator to my SER server, then it must go to a Nat Traversal server and finally to the UA client, but instead of that the ACK tries to go directly from SER to the UA in its local address 192.168.1.109, skipping the Nat Traversal server. The UA sends a BYE to the call because it never receives this ACK. I use another origination provider in the same scenario without problems. This other origination uses loose routing, and ACK messages go in the right path: origination -> SER -> Nat traversal -> UA. How can I resolve this strict routing problem? Thanks in advance, Rosa. _________________________________________________________________ Express yourself instantly with MSN Messenger!

[OpenSER-Users] openxcap question
by Klaus Darilion 19 Feb '08

19 Feb '08

Hi! If I PUT a document to http://1.2.3.4/@mydomain/org.openmobilealliance.pres-rules/users/test/pres-… and then PUT another document to http://1.2.3.4/@mydomain/org.openmobilealliance.pres-rules/users/test/pres-…, it will overwrite the first file, thus it does not matter if it is pres-rules or pres-rules2. Is this by design, a wrong configuration, or just a bug? thanks klaus

by kionez 19 Feb '08

19 Feb '08

Hi all, i'm trying to write some custom perl module to extend functionalities of openSER. I can't notify UAC with classic sl_send_reply, in my debug log i found: ERROR:core:moduleFunc: Module function 'sl_send_reply' is unsafe. Call is refused. ERROR:core:XS_OpenSER__Message_moduleFunction: calling module function 'sl_send_reply' failed. Missing loadmodule? in my perl script i put a simple: $m->moduleFunction("sl_send_reply", "200", "OK"); as i read in module's example i found in samples/function.pl file. there's some way to send replyes in perl scripts? thanks in advance. k.
