Hi, I would like to try use the module nathelper with rtpproxy to test when INVITE , voice (rtp) can pass nat and firewall, just like (http://www.informatik.uni-bremen.de/~prelle/terena/cookbook/main/ch04s07.ht… 4.7.3.5.1. SIP Express Router mentioned), but ser crashes after receive REGISTER but after REGISTER , ser crashe... ================================================================= syslog: BUG: 15 (23183) tcp_main_loop: dead child 5 0 (23168) child process 23173 existed by a signal 11 0 (23168) core was not generated 0 (23168) INFO:terminating due to SIGCHILD ... ... ================================================================= i install ser0.8.12 , and download newest nathelper , rtpproxy form berlios cvs Makefile rev 1.6 nathelper.c rev 1.51 nathelper.cfg rev 1.2 nathelper_rtpp.cfg rev 1.1 nhelpr_funcs.c rev 1.7 nhelpr_funcs.h rev 1.2 rtpproxy main.c rev 1.17 ... ... My environment is kphone 3.14 -------> Gateway(NAT+Firewall) ----Internet----Ser + rtpproxy kphone use UDP , Symmetric Signaling and Symmetric Media , not use STUN server my ser.cfg is the same as the link (http://www.informatik.uni-bremen.de/~prelle/terena/cookbook/main/ch04s07.ht… 4.7.3.5.1. SIP Express Router mentioned) besides one line if (method == "REGISTER" || ! search("^Record-Route:")) { ===> ser said it is wrong , i don't what's wrong...? so i modify it to if (method == "REGISTER") { My question is : 1. Does the idea (http://www.informatik.uni-bremen.de/~prelle/terena/cookbook/main/ch04s07.ht… 4.7.3.5.1.

Hi Jiri Thanks for the advice - it works perfectly now. I must say that out of the many Uas I have played with - more of them screw the tags up than less. Thanks again for the help.

If the to-tag in 2xx matches the one in dialog block then the dialog will transitioned to confirmed state and no tag updation happens effectively same tag used in further transactions in that dialog. If the To-Tag does not match any of the existing dialogs for that call then it creates a new dialog and stored in call block then that tag will be used in further transactions in that dialog which in turn part of the call. 13.2.2 Processing INVITE Responses If the dialog identifier in the 2xx response matches the dialog identifier of an existing dialog, the dialog MUST be transitioned to the confirmed state, and the route set for the dialog MUST be recomputed based on the 2xx response using the procedures of Section 12.2.1. but it only mentions about recomputing the route set, not the rest of the dialog state. -- juha _______________________________________________ Sip-implementors mailing list Sip-implementors(a)cs.columbia.edu http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors Confidentiality Notice The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain confidential or privileged information.

[Serusers] Call Parking
by Kapil Dhawan 02 Apr '04

02 Apr '04

How can i implement Call Parking Definition: Call parking allows you to park a call and pick it up at another location. Lets say 111 dialed 222 and now 222 somehow parked the call using some dial code (e.g 150) and now 222 can reach any other phone and can pick up the call by dialing call parking answer code (e.g. 151) + extension from where he parked.... How can i implement it in SER. is it already there... _________________________________________________________________ Easiest Money Transfer to India.

[Serusers] NAT and multiple proxy
by zeusng 01 Apr '04

01 Apr '04

Consider the following scenario: UA---NAT---Proxy1---Proxy2+UsrLoc User agent UA is behind NAT which send a REGISTER request to Proxy2 but was instructed to use Proxy1 as the first hub. Which of the two proxies should rewrite the contact header. Note that Proxy1 does nothing but to forward all requests to Proxy2, something like: Route[0] { check (max_forward_header & message_len); record_route(); rewritehostport(proxy2:port); t_relay(); } Zeus Ng
