Dear mailing list members,

*1 *After the update, errors of this type no longer appear "*ERROR:
ROUTE_BRANCH_ACC_RTP dialog [dialog.c:1868]:".


*2* Routing continues to fail in mr13.5.1.
  - Tests were performed up to mr8.5.12 and according to the interface
configuration discussed above, the call tests work correctly.
  - When testing from mr9.4.1 onwards, the signaling only works in one
direction, as originally indicated.
  - It appears to be a problem with the switch-internal network, which is
not passing information to interface neth3 type:sip_ext_incoming with
endpoints with public IPs.
  - Could this be a problem related to the change from version mr9.4,
specifically the change from SBC application to B2BUA?

I would appreciate any feedback that helps me implement my configuration
correctly.

Thank you..
