Hello. I have 2 pjsip enpoint configuration teampltes for webrtc users and softphone connection
[webrtc-endpoint-template](!)
type=endpoint
context=from-internal
disallow=all
allow=opus
webrtc=yes
rtp_symmetric=yes
rewrite_contact=yes
force_rport=yes
dtmf_mode=auto
direct_media=no
[nat-endpoint-template](!)
type=endpoint
context=from-internal
disallow=all
allow=ulaw
allow=alaw
transport=transport-udp
rtp_symmetric=yes
rewrite_contact=yes
force_rport=yes
dtmf_mode=auto
direct_media=no
and all worked perfect, but some users want to use Webrtc or softphone sometimes.
And I tried to make general template
[common-endpoint-template](!)
type=endpoint
context=from-internal
disallow=all
allow=opus
allow=ulaw
allow=alaw
webrtc=yes
rtp_symmetric=yes
rewrite_contact=yes
force_rport=yes
dtmf_mode=auto
direct_media=no
and one shoulder RTP and SIP work correct, but when one softphone call to another using common-endpoint-template
INVITE to second softphone(both softphones configured to support only ulaw, alaw codecs)

both endpoints had
allow : (opus|ulaw|alaw)
Does somebody had way how to merge endpoints configuration for Webrtc and softphones?
and fixed codec negotiation between 2 channels
