Re: [Kamailio-Users] ERROR:core:receive_msg: no via found in reply

Please open a bug with respect to this issue. This error should end up in the error_route. Try to run tcpdump with buffer rotation and see if you can spot the bogus reply.

[Kamailio-Users] Carrierroute and or LCR
by Stagg Shelton 14 Apr '09

14 Apr '09

I am preparing to add a new upstream SIP provider to my network, and now have a requirement to route based on the number that the user is calling. From what I have read it appears that LCR is the better method for doing this. I have one small issue in that I have a few customers who switch through my network in order to get to a specific carrier. Currently I am using carrierroute with all of my customers in order to support the ones that need to switch to specific carriers, and everyone else takes the default carrierroute. Can carrierroute and LCR be used together? If so can you give me a few pointers so that I can get a lab system working. If not can you suggest whether or not carrierroute could or should be used to route based on rate center. The rate center list from my new carrier is about 31,000 rows. If carrier route cannot or should not be used for this purpose, can you recommend a way that LCR can be used, and still have a few customers switch out to a specific carrier regardless of the number dialed? Thank You Stagg Shelton

HI All, Recently i installed Kamailio 1.5 everything working fine except the LCR module, found theer was no lcr.so module file in the module file. I tried to rebuild the module separtly also but didnt work. Is there any changes in this module in ver 1.5? Did anyone also had same problem, I tried on debian 5 as well as on Centos 5 with same result. Though there is no issue in insatallation of ver 1.4 in either of the machines.

[Kamailio-Users] How to calculate hash_index on DB carrierroute
by Uriel Rozenbaum 14 Apr '09

14 Apr '09

Hi gentlemen, I'm configuring some balance and failure routes with CarrierRoute module. I have the following topology: -----------> Carrier1 --------> GW1 -----------> Carrier2 Kamailio -----------> Carrier1 --------> GW2 -----------> Carrier2 The idea will be to select a carrier using carrierroute going out through GW1. If GW1 fails (timeout) i want the call to go to the same carrier through the other GW. I assume the hash value calculated on cr_route will be the same for the failure route, but I need to verify the fields used on the DB to calculate a hash_index and the way that they are calculated so I can assure the previous behavior. Thanks in advance! Uriel

Hi, When printing the message in function receive_msg() in core the buffer seems to be corrupt with CSeq header name. It shows as Seq and naturally the parsing fails throwing error as reply cannot be parsed and also no 2nd via found in reply.
