Audio Codecs
Check the desired codecs, all others will be disabled unless explicitly enabled in a device or
trunks configuration. Drag to re-order.
Non-Standard
g726
Asterisk: g726nonstandard. If the peer negotiates G726-32 audio, use AAL2 packing order
instead of RFC3551 packing order (this is required for Sipura and Grandstream ATAs, among
others). This is contrary to the RFC3551 specification, the peer _should_ be negotiating
AAL2-G726-32 instead.
T38
Pass-Through
Asterisk: t38pt_udptl. Enables T38 passthrough if enabled. This SIP channels that support
sending/receiving T38 Fax codecs to pass the call. Asterisk can not process the media.
Video Support
Check to enable and then choose allowed codecs. If you clear each codec and then add them one
at a time, submitting with each addition, they will be added in order which will effect the codec
priority.
