Hi We have a question. We are preparing a setup to bridge the SIP call from Kamailio IMS to PSTN, but we are puzzling how we can present the P-Asserted-Identity in the SIP INVITE. By default, the PAI is in sip:user@domain, but we believed we should use<tel> format in the PAI when bridge to PSTN. question is 1. should we have two PAI headers?, or 2. should we paste <tel> format in PAI User Part and domain in PAI Host Part?, or 3. Should we only use one PAI header with tel format? In our test setup, we are using FHoSS, and the IMPU sip:user@domain have below entry in "IMPUs from Implicit-Set" - sip:user@domain - tel:number Question is how we can extract the number from the HSS and presented in PAI? - RBK
