Кстати в новых релизах возможно достаточно заполнить Settings/Configuration/Public URL Branch
Но я делал по старому - через переменную, а это поле оставлял пустым.

Вот. что про это пишут в SOLN321384:
IMPORTANT NOTE :

Starting with Equinox Management 9.1.x release, a new field called Public URL Branch was added under Settings>System Preferences>Configuration.

This is where you would define the external reverse proxy FQDN specific to UCCP/UCCS communication that would come in over the SBC or hardware Load balancer.

It is recommended to dedicate a separate interface and reverse proxy rule for UCCS, but in customer scenarios where it is not possible and the AAWG/User Portal reverse proxy public FQDN is being used, then the Public Branch FQDN on Equinox Management should accordingly be defined to point to AAWG.

Note that even though the field says Public Branch FQDN, it is used for both internal and external legs and hence DNS split horizon and/or SBC internal reverse proxy should be employed as necessary.

There is also a know issue with this particular field in the current versions leading upto 9.1.9 where simply defining that field is not sufficient and will not update the UCCP URL, which will still use the internal FQDN is some cases.

In such cases, the Advance Parameter mentioned in the Solution above should be used. This will be addressed in a future release so that the Advance Parameter definition may not be required.
