Why codec negotiation isn't working with dial plan variables SIP_CODEC_OUTBOUND/SIP_CODEC_INBOUND in Asterisk 18.2.1

Asterisk Asterisk SIP

Am using Asterisk 18.2.1 and pjsip. Am trying to mandate audio codecs in the dialplan as below, but not getting the expected results. Please help.

exten = 108,1,Answer()
same = n,Set(SIP_CODEC_INBOUND=alaw)
same = n,Set(SIP_CODEC_OUTBOUND=alaw)

The reason is you are trying to use chan_sip functionality with chan_pjsip, which won’t work. PJSIP has the media offer dialplan function[1] which has some of the functionality.
