Audio Connection Delay with SCA
Hi, I finally got Shared Call Appearance working to 4 NAT connected phones!!!!! Now the users say when they answer that line, they must wait a second or so to start talking (no big deal), but they all claim it takes nearly 5 seconds to be able to hear the caller. They answer the standard "Thank You for calling XYZ, how can I help you today" which the caller DOES HEAR, but they cannot hear his response for the first 5 seconds and ALWAYS have to ask them to repeat it. In the logs, I see what I believe is them picking up extension 299: 2012-06-08 11:44:15.115249 [NOTICE] switch_channel.c:926 New Channel sofia/external/sip:299@69.251.170.6:5063 . And then the RPT finally connecting: 2012-06-08 11:44:20.665094 [DEBUG] sofia_glue.c:3248 AUDIO RTP [sofia/external/sip:299@69.251.170.6:5064] 10.10.40.185 port 23500 -> 69.251.170.6 port 16498 codec: 0 ms: 20 Note the 5.5 second delay! Granted there are 100+ lines between those if you want to see them, I will post them. After that audio is fine. Any thoughts would be appreciated. Sean
what type of phone? If it has a jitter buffer, you can try reducing or disabling it. its probably a combo of jitter buffers charging up on the phone, and the auto-ajust trying to fix the broken sdp for NAT. On Fri, Jun 8, 2012 at 12:12 PM, Sean Devoy <sdevoy@bizfocused.com> wrote:

Anthony, Thanks for the reply. We use all CSICO SPA504G phones. I did have the jitter buffer set up "HIGH" (choices: Low, Med, High, Very High, Extremely High). I dropped them down to Low now for testing. They do have pretty good network speeds (business level cable modem). There is also something labeled: " Jitter Buffer Adjustment: " Choices (Up, Down, Both, Disabled). I have both. However, the issue is present, but far less pronounced in non-shared lines. They have always said there was a connection delay at this site, but with SCA it seems to be compounded. Maybe Group Call Pick will work better for them, they are all in the area.

from FS point of view there should be little different from SCA and not SCA besides the presence signaling, you should try some on-site testing with the same phones. On Fri, Jun 8, 2012 at 2:52 PM, Sean Devoy <sdevoy@bizfocused.com> wrote:

FYI: New System w/ 2 Hyperthreaded Dual core 3.0Ghz XEON processors (vs P4 3Ghx) appears to have solved this delay problem. -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Anthony Minessale Sent: Friday, June 08, 2012 4:00 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] Audio Connection Delay with SCA from FS point of view there should be little different from SCA and not SCA besides the presence signaling, you should try some on-site testing with the same phones.
