[Kamailio-Users] Help!! Getting get_hdr_field: out of memory
by Krunal Patel 09 Jan '09

09 Jan '09

Hi, I am using openser 1.2.3. I have increased PKG_MEM_POOL_SIZE to 4MB. Openser worked properly for 4 days since last restart. I found get_hdr_field: out of memory for all messages. I did openser restart & the issue is fixed now. Is anybody there who have faced the same issue? Thanks in advance!! -- Krunal patel

[Kamailio-Users] Internet drops and ATA don´t register
by MagoDaViola 09 Jan '09

09 Jan '09

Untitled Document Hello all .... I'm having a problem with our server or customers. Most of our clients access the server using the combination ATA and ADSL Modem, but when the ADSL drops and returns in a few minutes, the ATA can no longer make the register on SIP server. Sometimes passing through the modem or the requests of the ATA. I identified that this happens a lot with the D-Link modems DSL-500B and siemens SpeedStream 4200. If someone went through this I would your help ... thanks … [View More]

[Kamailio-Users] Accounting: How to avoid a fraudulent BYE with lower CSeq?
by Iñaki Baz Castillo 08 Jan '09

08 Jan '09

Hi, first of all I'm sorry for this cross-posting, but I think it could be interesting for any SIP proxy with accounting capabilities. I'm thinking in the following flow in which the caller/attacker would get an unlimited call (but a limited CDR duration): -------------------------------------------------------------------------- attacker Kamailio (Acc) gateway INVITE (CSeq 12) ------> <-------- 407 Proxy Auth INVITE (CSeq 13) ------> … [View More] INVITE (CSeq 13) ------> <------------------- 200 Ok <------------------- 200 Ok << Acc START >> ACK (CSeq 13) -----------> ACK (CSeq 13) -----------> <******************* RTP ************************> # Fraudulent BYE !!! BYE (CSeq 10) -----------> << Acc STOP >> BYE (CSeq 10) -----------> <-- 500 Req Out of Order <-- 500 Req Out of Order -------------------------------------------------------------------------- The call hasn't finished, but Kamailio has ended the accounting for this call since it received a BYE. And this BYE will generate a correct ACC Stop action (since it matches From_tag, To_tag and Call-ID). I think this is *VERY* dangerous and I hope I'm wrong. Would help the dialog module here? does the dialog module check the CSeq of the BYE in some way and could it prevent Kamailio from generating the ACC STOP action? (I don't think so). I've also asked in SIP-implementors and an idea could be generating the ACC STOP action when receiving the 200 OK for the BYE (and not when receiving the BYE itself). Of course this will be valid when the gateway is the recipient of the BYE (and we know the gateway is not an "attacker"), but this is not valid when the recipient of the BYE is an user since it could send no reply for the BYE. The only solution I see is: - Using the dialog module, Kamailio should check the CSeq value in the BYE. 1) Kamailio should forward the BYE just in case the CSeq is higher than the actual CSeq for this dialog direction. 2) Kamailio should generate the ACC STOP action just in case the CSeq is higher than the actual CSeq for this dialog direction. Both 1) and 2) are needed since a gateway could accept a BYE with wrong CSeq. In this case the call is ended but the accounting STOP action doesn't exist (infinite call). But I think this is too complex, isn't it? -- Iñaki Baz Castillo <ibc(a)aliax.net> [View Less]

[Serusers] SER server reload
by Leon Li 08 Jan '09

08 Jan '09

Dear all, I am new to SER and on a project to reload company's SER server for some SIP testing. However, I couldn't start SER after compiling. Every time I run "/usr/local/sbin/ser -f /PATH/ser.cfg", I got "ERROR: bad config file (1 errors)". Does this mean my ser.cfg has something wrong or where can I trace the logs for errors? Also, how do I uninstall the old SER and run a clean installation? Any suggestion would be appreciated. Best regards, Leon Leon Li | IT … [View More]

[Kamailio-Users] carrierroute prioritize gateways
by Juan Asencio 07 Jan '09

07 Jan '09

Hi list, I'm reading some old post in order to implement carrierroute. I found this in a post that I include at the end of this message, but the part that I want to ask about is this one: "You can put all the carriers under the same table and prioritize the gateway based on domains. Like tis you don't need to hardcode anything in the config file" If I do this, do I need to prioritize the gateways on the subscriber table and if is there, how do I do it for the domain, when it is only a … [View More]
