Hello Everyone, I want to change ptime configuration. Will anyone assist me to change ptime value 20 to 40 for codec PCMU,PCMA ? FLow : *SIP-PHONE---Ptime(20)-->FS server (Need to change Ptime to 40) ---------->To Provider* NOTE : If I send 40 Ptime From SIP-PHONE then Call quality is Good but for this i need to change all phones' ptime and I don't want to change it manually.So I need to change this From FS Side. Currently I can see below log in freeswitch logs : m=audio 8000 RTP/AVP 98 97 8 0 3 101 a=rtpmap:98 speex/16000 a=rtpmap:97 speex/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:3 GSM/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=ptime:20 Dialplan: sofia/default/4602534812@192.168.1.26 Action bridge(sofia/gateway/localgateway/001***) m=audio 24716 RTP/AVP 8 101 13 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 a=sendrecv I tried different solutions for this issue but no luck. 1. Add below line before Bridge Channel set(absolute_codec_string=PCMU@8000@40i,PCMA@8000@40i) 2. Add below line before Bridge Channel set(absolute_codec_string=PCMU at 8000@40i,PCMA at 8000@40i) 3.Change below parameter in SIP profile 1.outbound-codec-prefs=PCMU,PCMA to outbound-codec-prefs=PCMU@8000 @@40i,PCMU@16000@@40i,PCMU@32000@@40i,PCMA@8000@40i,PCMA@16000 @40i,PCMA@32000@40i 2.outbound-codec-prefs=PCMU,PCMA,rtp-autofix-timing=false 3.outbound-codec-prefs=PCMU,PCMA,absolute_codec_string=PCMU at 40i,PCMA at 40i,rtp-autofix-timing=false 4.outbound-codec-prefs=PCMU at40i,PCMA at 40i 5.outbound-codec-prefs=PCMU at 8000h@40i,PCMA at 8000h@40i ,inbound-late-negotiation=false 6.outbound-codec-prefs=G729,PCMU,PCMA,inbound-late-negotiation=false Please point me where i am doing wrong. -- Thanks, Bhavik Patel
