Table 5-3: ini File Coder Parameter

Parameter Description

CoderName

Enter the coders in the format: CoderName=<Coder>,<ptime>.

For example:

CoderName = g711Alaw64k,20

CoderName = g711Ulaw64k,40

CoderName = g7231,90

Note 1: This parameter (CoderName) can appear up to 10 times.

Note 2: The coder name is case-sensitive.

You can select the following coders:

g711Alaw64k – G.711 A-law.

g711Ulaw64k – G.711 µ-law.

g7231 – G.723.1 6.3 kbps (default).

g7231r53 – G.723.1 5.3 kbps.

g726 – G.726 ADPCM 32 kbps (Payload Type = 2).

g729 – G.729A.

g729_AnnexB – G.729 Annex B.

Note: If the coder G.729 is selected, the gateway includes ‘annexb=no’ in the SDP of the

relevant SIP messages. If G.729 Annex B is selected, ‘annexb=yes’ is included. An

exception to this logic is when the remote gateway is a Cisco device (IsCiscoSCEMode).

The RTP packetization period (ptime, in msec) depends on the selected coder name, and

can have the following values:

G.711 – 10, 20, 30, 40, 50, 60, 80, 100, 120 (default=20).

G.729 – 10, 20, 30, 40, 50, 60 (default=20).

G.723 – 30, 60, 90 (default = 30).

G.726 – 10, 20, 40, 60, 80, 100, 120 (default=20).
