I’m using PJSIP. It looks like the "Digest realm=“xxx.xxx.xxx.xxx” part of my outbound authentication challenge can be one of four servers. I cannot figure out a way to have my outbound_auth support multiple realms. (sorry no trace without breaking the system.)
Here’s the auth and endpoint:
[ZZZZZZ] type=endpoint transport=transport-udp-nat context=from-external disallow=all allow=ulaw outbound_auth=sipus_auth aors=sipus_aor direct_media=no from_domain=sip.aserver.com [sipus_auth] type=auth auth_type=userpass password=xxxxxxxxx username=xxxxxxxxx realm=sip.aserver.com
BUT CAN BE ONE OF THESE TOO (I’ve already seen one other)
These are IP addresses published in a “white list”.
So it looks like I need a way to have one auth support three realms.
