Re: [sr-dev] [kamailio/kamailio] lost: dynamic HELD url resolving (#2574)

Yes, looks as it will be a good extension. Domain from `From` header may be used only if domain not available in `P-A-I` header. Here examples of `From` and `P-A-I` headers that we can receive **Example 1** - domain matched in `From` and `P-A-I` headers ``` From: <sip:+18556667788@206.147.246.118:5060>;tag=gK0e0d09a4 P-Asserted-Identity: <sip:+18556667788@206.147.246.118:5060> ``` **Example 2** - private IP address in `From` header and no domain in `P-A-I` header. `P-A-I` contains tel and sip uri. ``` From: <sip:+16692481432@198.226.45.84>;tag=gK04090b5e P-Asserted-Identity: <tel:+16692481432>, <sip:+16692481432@vzimstest.com> ``` **Example 3** - IPv6 address in `From` header and no domain in `P-A-I` header ``` From: "9255111003"<sip:9255111003@[2605:97c0:2058:3120:1::1]:50001>;tag=75fdbcf61a;epid=SC597fbd P-Asserted-Identity: <tel:9255111003> ``` **Example 4** - no domain in `From` and `P-A-I` headers ``` From: <tel:+13559598013>;tag=SDtl3t701-5f7f754a-5f89c26229204b60-Noo-lucentNGFS-000264 P-Asserted-Identity: <tel:+11005534340> ``` Think not required to make double reverse and NAPTR DNS lookups if the domain from `P-A-I` or `From` headers equals to caller network IP address. Could you look at this example. ``` P-Asserted-Identity: <tel:+16692481432>, <sip:+16692481432@vzimstest.com> ``` IP address does exist here, put present caller domain. So we can skip reverse lookup and execute NAPTR. -- You are receiving this because you are subscribed to this thread.
