[asterisk-bugs] [JIRA] (ASTERISK-26782) res_pjsip: URI requirement for fields is not consistently documented and error does not provide indication

Richard Mudgett updated ASTERISK-26782:
---------------------------------------

    Description: 
In chan_sip the outbound proxy could be entered as IP address. Howewer with PJSIP when
outbound_proxy=80.x.x.152
is used, the registration section will not load.

Using URI as proxy, the problem is solved:
outbound_proxy=sip:80.x.x.152:5060

While this requirement is valid and partially documented, there are the following problems:
# The other items in pjsip.conf that have to contain URI have _uri in their name, so they are self-explanatory. For outbound_proxy, the URI requirement is only documented for endpoint in the pjsip.conf.sample, but not for registration and aor.
# The error end debug messages generated when an IP instead of URI is used does not really give any hint about the problem and makes solving this very difficult:

# Registration/endpoint/aor item is not (re)loaded when the IP is used as outbound_proxy. However on PJSIP reload the old configuration for the Registration/Endpoint remains active and no changes from pjsip.conf are applied for this Registration/Endpoint. On restart of asterisk, the whole Registration/Endpoint is not loaded. This gives an inconsistent behavior. Depending whether reload or restart is done, the registration/endpoint/aor is there or not. I would expect in both cases the complete Registration/endpoint/aor to be removed from the active configuration instead of keeping the old state in the case of reload with errors in pjsip.conf.
