Hello everyone,

...

From today i started getting SIP 480 error when making outbound call.

I checked out with a different voip provider and got SIP 500 error. Internet calling is working fine. The service (outbound calls) was working fine till yesterday. I'm a newbie to kamailio and voip, so need your help. Please guide me to resolve this error. Thanks in advance.

Which reinforces the idea that there is something about the request that the providers don't like, but which is not a grammatical error. Everyone has their favourite way of making packet captures of signaling flows. Mine is to use tcpdump: tcpdump -i any -A -s 0 -n 'udp port 5060' (on the Kamailio server) On 7 April 2014 21:32:17 CEST, Amogh meshram <pacifire01(a)gmail.com> wrote:

Hello, It's just a guess, but I think most SIP providers aren't going to like the all-zeroes Caller ID/ANI that you're sending here: Contact: <sip:0000000000@1.22.216.96:35465;transport=UDP> This is especially true since their routing is influenced by CLID, due to the possibility of intra/inter-jurisdictional rate differences. -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/

In that case, you've got a mystery on your hands, and should take it up with the providers--unless I missed something in your invite. On 04/07/2014 03:57 PM, Amogh meshram wrote:

Providers don't have any issues with caller id's. We can even call from a single digit. And even if a sip account is not associated with a caller id (a number) rather its just a name (as skype id like xxx.yyy) when initiated a pstn call, the providers use local numbers (if ur gateway is in germany then the proivder will use a germany number) to call and the receiver will that local number.
