We are using our own softphone, based on an SDK from Port SIP (www.portsip.com).
The softphone uses to send RPT Payload 126 as RTP Keepalive, and at the asterisk console we get the following message:
NOTICE[-1] res_rtp_asterisk.c: Unknown RTP codec 126 received from ‘172.16.2.56:21520’
Any ideas on how to fix this?
I’m using Asterisk Ver. 184.108.40.206
