George Joseph has uploaded a new change for review.

Change subject: res_pjsip/config_transport: Prevent async_operations > 1 when protocol = tls
......................................................................

res_pjsip/config_transport: Prevent async_operations > 1 when protocol = tls

See ASTERISK-25615.
If the transport protocol is tls and async_operations > 1, pjproject
will segfault if more than one operation is attempted on the same socket.
Until this is fixed upstream, a check has been added to throw an error
if a tls transport config has async_operations set to > 1.

ASTERISK-25615 #comment Work-around until fixed upstream
