Sylantro servers and ININ servers require specific configuration methods for
per-line configurations.
For Sylantro Server
When configuring the BLA feature on a per-line basis for a Sylantro server, the
value set for the "sip lineN bla number" parameter shall be the same value set for
the "sip lineN user name" parameter for all the phones in the group. For example,
if sip lineN user name is 1010, you would configure BLA on a per-line basis for
the Sylantro server as follows:
sip line 1 mode: 3
sip line1 user name: 1010 (
# for all the phones)
sip line1 bla number: 1010
