5.64. Codecs
The sofswitch can route any audio, video and fax codecs.
In the endpoints (MAgent, GSM Gateway, etc) the following codecs are supported by default (in this order):
1. G729/G729.A
2. G723.1
3. PCMU
4. PCMA
Voice recording, “voice here” and conferencing feature will work only with these codecs.
In GSM gateways some other codecs are supported as well and must be enabled on request (such as GSM, G726, Speex).
5.65. How to reserve GSM capacity for a certain protocoll
In the global configuration you have to set the following keys:
reserveforh323: number of channels to be reserved for traffic received from H323;
reserveforsip: number of channels to be reserved for traffic received from SIP.
On packet and gateway level you can specify the maximum number of reserver channels from that packet by setting the “maxalloc” field (defaults to 0!).
When set properly, the server will reallocate the requested best quality channels for the requested direction in every hour.
To manually reserve capacity for sip set the reserverfor field in tb_sims to 1 on the required channels.
