On the receiving SMG the following actions must be performed:
1.
Create a new interface in 'Routing -> SIP interfaces' section:
1.1.
Set 'Transit E1' mode on the interface;
1.2.
Set IP address of the remote side;
1.3.
Set signalling destination port on the remote side;
1.4.
Set signalling receive port;
1.5.
Select network signalling interfaces and RTP;
1.6.
Select appropriate codecs in 'Codecs configuration/RTP' tab, if it is necessary;
1.7.
Click 'Apply'
2.
Select a stream in 'E1 streams' section and perform the following settings:
2.1.
Signalling protocol - SS7;
2.2.
Physical parameters - Enabled;
2.3.
Move to 'Channel settings' tab;
2.4.
Click 'Edit' in 'Transit' column of the channel which will be configured;
2.5.
Check 'Enable transit';
2.6.
Select codec which will be used for connection. If you select 'by default', the codecs which
were set on the selected SIP interface will be used.
2.7.
Select SIP interface which were configured in 1 step;
2.8.
Define E1 stream and number of a channel on remote side to which connection will be
implemented;
2.9.
Click 'Apply' in transit configuration window;
2.10.
Click 'Apply' in 'Channel configuration' section.
On the SMG which establishes the connection 1 and 2 steps must be performed as for receiving SMG, but
