Re: [Freeswitch-users] ptime problem with provider (Cisco hardware)
The pvalue of the originator overrides whatever you might have configured on Cisco GW. -Original Message- From: freeswitch-users-boun...@lists.freeswitch.org [mailto:freeswitch-users-boun...@lists.freeswitch.org] On Behalf Of Pablo Hernan Saro Sent: 21 March 2009 03:16 To: freeswitch-users@lists.freeswitch.org Subject: Re: [Freeswitch-users] ptime problem with provider (Cisco hardware) I am not a Cisco expert, but as far as I know packetization period is configurable in Cisco. When you specify the codec for a dial peer, you can set up the ptime value in milliseconds. This is an optional argument in the Cisco command line and what happens when providers don't specify it is that your end assumes a convenient or default ptime value, that probably don't match with far end default... A solution would be to figure out what is the convenient value for an individual provider and set up FS to match it, or suggest your provider to specify a ptime in the first request. By the way, Cisco supports 10, 20, 30, 40, 50 and 60 as ptime values for codecs G.729, G.729A, G.729B and G.729AB.

Hi, This is a known issue with some of these platforms but for completeness can you send the actual SDP? 2009/3/19 Łukasz Czerpak luk...@czerpak.eu: Hi, I have some troubles with provider configuration. The are warnings in logs: 2009-03-19 19:02:48 [WARNING] mod_sofia.c:739 sofia_read_frame() We were told to use ptime 20 but what they meant to say was 40 This issue has so far been identified to happen on the following broken platforms/devices: Linksys/Sipura aka Cisco ShoreTel Sonus/L3 We will try to fix it but some of the devices on this list are so broken who knows what will happen.. My provider uses SER and Cisco hardware (Cisco-SIPGateway/IOS-12.x). Moreover, above warning appears only when someone calls to FreeSWITCH (voice quality is poor) - connection from FreeSWITCH works without any warnings and has perfect quality. Other my providers works perfect.

The issue I seen was they invite to you with NO ptime which indicates 20ms, they should invite with ptime:60 if they want 60. /b On Mar 19, 2009, at 3:06 PM, Łukasz Czerpak wrote: I've just tested g...@60i and everything works perfect - thank you very much.
