Re: [SR-Users] Not able to replace route_uri in contact header uri

Hi Daniel, I am attaching here my sip trace at client side.Request you to see this. My client IP in register request is 125.16.231.74 and the server on which kamailio is running is 185.122.205.178. I want my contact header to be <sip:OTT919620649614@185.122.205.178:5070;lr> I am using avp_subst() function to replace this.But kamailio is not starting.

Please reply if I am in wrong way or have different understanding as I am very new to kamailio.

I mean to say, In my register request the route header i.e. route_uri is <sip:185.122.205.178> and contact header is 3333(a)172.22.13.41. I want my contact header to be 3333(a)185.122.205.178. So how can I replace the contact header's only domain part with route_uri.the user part of the contact header remains same.

I put some logs on route[REGISTRAR] and able to see the $route_uri as kamailio server uri($avp(s:fs) and $hdr(Contact) as pjsip server uri ($avp(s:contact).But I am not able to replace the uri with avp_subst() function. Can anybody help me how to replace the uri or with any any other function. Below I have put the snippet of config file. # Handle SIP registrations route[REGISTRAR] { if (!is_method("REGISTER")) return; if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); #!ifdef WITH_NATSIPPING # do SIP NAT pinging setbflag(FLB_NATSIPPING); #!endif } xlog("Narayan: before sending contact\n"); $avp(s:contact) = $hdr(Contact); $avp(s:fs) = $route_uri; xlog("Narayan: Forced socket is $avp(s:fs)\n"); xlog("Narayan: contact header is $avp(s:contact)\n"); avp_subst("$avp(s:contact)/avp(s:contac)/g", &quot;/(.*)(a)(.*)/$route_uri/&quot;)ri/"); #avp_pushto("$ru/domain","$fd"); #rewritehostport("185.122.206.62:5060"); t_on_reply("MANAGE_REPLY"); t_relay(); #if (!save("location")) { # sl_reply_error(); #} exit; } Any suggestion will be highly appreciated.
