Error in kamailio 5.3.3
by Pavithra M 08 Apr '20

08 Apr '20

Hi, I have configured kamailio as Ims server with pcscf,icscf,scsf and hss in 4 different vms . After that I use zoiper client for testing the call flow . Registration is successful .It goes via UE -> Pcscf -> icscf -> scscf and returns back with 200 OK . Registration is happening with authentication from hss . When I make an INVITE , it goes from UE -> PCSCF -> SCSCF -> ICSCF -> SCSF and s-cscf gives *403 - Domain not served *to icscf and i-cscf returns to p-cscf with the same error . I am not seeing any errors in scscf and i-cscf . In pcscf , I am seeing an error like *Error : <core> [core/lvalue.c] :lval_pvar_assign() : setting pvar failed * *Error : <core> [core/lvalue.c] :* *lval_assign():assignment failed at pos* What should I do? Kindly advise. I am struggling with this issue for a week.kindly do the needful. Version - kamailio - 5.3.3 I need a normal call flow to be established between two clients.kindly help .

In theory, it should all be FIFO, of course. In practice, there are stochastic aspects to OS process scheduling and I/O scheduling which make the ingress and egress of messages arriving at Kamailio simultaneously or substantially simultaneously somewhat indeterminate. And, of course, it depends on how complicated the processing of the messages respectively is, either in computational terms, or external I/O wait, or both. To Steve Davies' point, that's just the nature of the multiprocess architecture, together with the lack of a distributor thread. -- 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/

We have a buggy endpoint that consistently sends reinvites immediately following the e2e ACK, and substantially simultaneously with the ACK. It quite often happens that the re-invite goes out the door before the ACK, which is of course rejected by the target due to inconsistent state. We solved this a somewhat nasty hack using just the very technique you mentioned -- we use the async features of Kamailio to 'delay' all re-invites about 50 ms. It does solve this problem, if a bit suboptimally and at the cost of eccentricity and complexity. -- 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/

KEMI - "record_route_advertised_address" - function export or alternative
by Jacob Greene 08 Apr '20

08 Apr '20

Hello all! I'm wondering if there are any plans to add record_route_advertised_address() function to KEMI? I'm unable to completely finish my migration to KEMI without this function due to server side NAT in our VPC and the record_route header getting automatically set to the advertised address. Is there a workaround I could use to change the record route header? Is anyone aware of any resources we could utilize to help get this fixed? Thanks for reading! Jake, Voice Engineer

Reloading Contacts/Attributes at runtime
by Sergiu Pojoga 07 Apr '20

07 Apr '20

Hi there, Is there some mechanism to reload Contacts *and *their attributes at runtime, without a full Kamailio restart? Known to me tools: *rpc ul.add* will add a new Contact, but not its attributes *rpc ul.flush* will flush from memory to DB, not the other way around Having a combination of registered/permanent Contacts, I can add permanent ones with *ul.add*, however I couldn't find a way to set its attributes other than in DB location, which implies the need for a reload. Thanks in advance. --Sergiu

Substitution of Contact Header
by Mack Hendricks 07 Apr '20

07 Apr '20

Hey All, I always have issues with substituting out header values. I’ve tried subst and subst_hf. Here is the value that I want to change out: Contact: <sip:52.41.52.34:5060;line=sr-h06Cy7RYRFkYacM0a7epa7sVa7sVRcNCW7IbaGZ9RGlC <sip:52.41.52.34:5060;line=sr-h06Cy7RYRFkYacM0a7epa7sVa7sVRcNCW7IbaGZ9RGlC>> And this is what I want it to be Contact: <sip:1313717555@jump.dsiprouter.net <sip:1313717555@jump.dsiprouter.net>;line=sr-h06Cy7RYRFkYacM0a7epa7sVa7sVRcNCW7IbaGZ9RGlC> I’m using this subst('/^Contact: <sip:(.*);(.*)>$/Contact: <sip:1313717555@jump.dsiprouter.net;\2 <sip:1313717555@jump.dsiprouter.net;\2>>\r/ig’); And it doesn’t work, but putting into a online regular expression tester it looks good as shown below. Any ideas?
