If you're already passing G729 through, including G729@40i in the list should override the ptime. Check the SDP on the outbound leg of the call to confirm. ________________________________ From: freeswitch-users-bounces@lists.freeswitch.org <freeswitch-users-bounces@lists.freeswitch.org> on behalf of bhavik patel <bhavikpatel14388@gmail.com> Sent: Monday, 24 August 2015 17:29 To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] Change ptime value Is it possible i can change it for G729 codec ?

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.
