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 exam-
ple, 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
For ININ Server
When configuring the BLA feature on an ININ server, the value set for the sip lineN bla number parameter shall be the
same value set for the sip lineN user name parameter without the incremented digit added to the phone #. For example, if
the sip lineN user name for the first phone is 10101, and the sip lineN user name for the second phone is 10102, etc., you
would configure BLA on a per-line basis for the ININ server as follows:
(# for phone 1 with appearance of phone 3)
sip line1 mode: 3
sip line1 user name: 10101 sip line1 bla number: 1010
(# for phone 2 with appearance of phone 3)
sip line1 mode: 3
sip line1 user name: 10102
sip line1 bla number: 1010
(# for phone 3)
sip line1 mode: 3
sip line1 user name: 1010
