Re: [sr-dev] [kamailio/kamailio] SCSCF failing to send INVITE to application server. (Issue #3015)

Hi, UE is sending INVITE with tel URI, and this tel URI is converted into SIP before reaching term-SCSCF ("tel2sip" function converts tel uri to sip uri). URI is converted to SIP with "user=phone" parameters appended to it.(coverted URI:-"sip:405874000000955@ims.mnc874.mcc405.3gppnetwork.org;user=phone"). We observed that, kamailio treats user=phone URIs as tel URIs, following is the code snippet ``` /* translate user=phone URIs to TEL URIs */ int phone2tel = 1; ``` sip-router-oob.cfg file has following comment ``` phone2tel=no # ignore user=phone in request-URIs -- otherwise # these URIs would be interpreted as equivalent # to TEL URIs, and their lookup would fail in URI # database ``` We were facing same issue, as it was failing in lookup for application server's information from database. After setting phone2tel=0, issue got resolved. SCSCF used SIP URI for lookup, it could retrieve application server's information and INVITE was sent to application server. #### We wanted to know that why "user=phone" URIs are treated as tel URIs ? Is there any specific reason for this consideration? -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3015#issuecomment-1028940915 You are receiving this because you commented.
