Hi,
I notice that whenever SER is binding UAs, everyone who register / invite at that time will just get stucked for a few seconds.
SER will not response when it's binding UAs
Is this normal? Anything can be done to improve this situation? Thanks in advance
Regards,
Chia
Hello to all, Im having huge problems connecting Cisco IP phones (7940 and 7960) to my SER. I m using the 7.5 SIP firmware. Before that, all phones (softphones, hardphones,...) worked, but the Ciscos seem to have problems to register and to make calls. The bigger problems are in the RTPproxy part of my ser.cfg.... the Cisco IP phones cant get out of this:
if (method=="REGISTER" && nat_uac_test("3")) { fix_nated_contact(); log(1, "LOG: ciscos doesnt work with NAThelper \n"); force_rport(); setflag(2); };
The phones dont register with SER when I have "force_rport". The phones cant make calls between them if I have "fix_nated_contact" and "force_rport"
If someone could manage to put Cisco IP phones to work with RTPproxy and NAT helper, please give me a hand. Thanks Joao Pereira www.fccn.pt
Hi Joao!
You have to provide some network dumps (ngrep port 5060). Otherwise we can'T figure out what the problem is.

Theres the ngrep. The phones try to register, but they cant...in the ngrep theres a "Ok", but the phones are not registered. SER is not asking for passwords of login names. If I comment the "fix_nated_contact" and "force_rport" It registers and works, but I want to use SER as a proxy.

I work with 7905G and mediaproxy. I had problem with first "if" that before it was in other location into ser.cfg.
route[2] { # ----------------------------------------------------------------- # REGISTER Message Handler # ----------------------------------------------------------------- sl_send_reply("100", "Trying"); if (!search("^Contact:[ ]**") && client_nat_test("7")) { setflag(6); fix_nated_register(); force_rport(); }; if (!www_authorize("","subscriber")) { www_challenge("","0"); break; }; if (!check_to()) { sl_send_reply("401", "Unauthorized"); break; }; consume_credentials(); if (!save("location")) { sl_reply_error(); }; }

This is a shoot in the blind.
in settings,sip-settings, and, number 24 and 25 (NAT Enable and NAT Address)
make sure NAT Enable is YES, and NAT ADdress is nothing. This I know work on firmware 6. -> 7.5.
The Cisco 7960 on my desk works fine behind nat so :-)

Joao,
One problem I see is that you're calling fix_nated_contact() when processing REGISTER messages.
This is actually illegal because the RFC says you can't change the contact header.
Therefore you should call fix_nated_register() instead.
