Enable the preferPtimeInSdp
flag to ensure that when the SBC sends out a ptime value in SDP, it gives preference to the ptime value it received in the a=ptime attribute in the incoming SDP over the a=maxptime value. This flag should be enabled in conjunction with the IP Signaling Profile flag sendPtimeInSdp
which enables the SBC to send out an a=ptime value. Enabling the preferPtimeInSdp
flag then ensures that the SBC sends out the a=ptime value if both values are received in the incoming SDP. The options are:
disabled
(default)enabled
Note: When configuring, if you enable sendPtimeInSdp
on the egress trunk group, enable preferPtimeInSdp
on the ingress trunk group, and vice versa.
