IP Interface Features

No need to use MGI card

There is no need to use MGI card for SVMi-20i to operate with IP phones or IP trunks. It

connects to IP phones or IP trunks directly. The IP address of SVMi-20i should be set and

LAN connector should be connected with the network that the main system connected.

NOTE: MGI card is still required to use some conference features for example, VMAME,

VMMOH and overhead paging.

NOTE: OfficeServ Systems always monitors the LAN connection with SVMi-20i. If there is a

problem with the connection(for example, no configuration, bad cable), MGI card is used for

SVMi-20i card to connect to IP phones or IP trunks.

sRTP

SVMi-20i supports sRTP for RTP stream with IP phones or trunks. It supports AES algorithm

for all countries and also supports ARIA algorithm for Korea. It requires more resources than

RTP, so maximum guaranteed VM/AA ports are 16. OfficeServ Systems do not limit to use

over 16 sRTP VM/AA ports, but the quality can be bad if more than maximum guaranteed

ports are used.

T.38 Fax

SVMi-20i can send or receive fax documents via IP network. It supports T.38 protocol or

G.711 passthrough. The DSP options should be set to select which way to use send or receive

fax documents. If G.711 passthrough is set, the codec is automatically changed to G.711 if the

codec is not set as G.711 when transmitting fax documents.
