### Troubleshooting

#### Reproduction

``` function send_options() local KAM_DOMAIN = "192.168.100.131" -- length(callid) is 129 local callid = "0123456789-0123456789-0123456789-0123456789-0123456789-0123456789-0123456789-0123456789-0123456789-0123456789-0123456789-0000000" local tu = "sip:1001@" .. KAM_DOMAIN local sut = "sip:192.168.100.132:5080"

KSR.pv.sets("$uac_req(method)", "OPTIONS") KSR.pv.sets("$uac_req(callid)", callid) KSR.pv.sets("$uac_req(furi)", "sip:" .. "kamailio" .. "@" .. KAM_DOMAIN) KSR.pv.sets("$uac_req(ruri)", tu) KSR.pv.sets("$uac_req(turi)", tu) KSR.pv.sets("$uac_req(ouri)", sut) KSR.pv.seti("$uac_req(evroute)", 1) KSR.uac.uac_req_send() end ```
