Re: [Freeswitch-users] DTMF Digits Lost when Under Load
Hi All,
Thought I would share my solution to this DTMF problem: it turns out my
ISP was capping my bandwidth & dropping packets to keep the connection &
1Mbps, so the experienced DTMF loss was actually packets being discarded.
On my way to this discovery I tested Freeswitch & DTMF quite thoroughly &
never actually found any problems even at hundreds of concurrent calls.
Here is how I tested, who knows this might be useful to someone:
- I used SIPp to generate calls & a Python script to log the received
DTMF digits
- SIPp command line:
- sipp -sf dtmfSenario.xml -d 1 -s 451 -l 96 -mp 5606 -i
xxx.xxx.xxx.xxx
- dtmfSenario.xml below
- Dialplan:
-
- Python:
- import sys
from freeswitch import *
def get_number(session,invalid,num=20):
digits = session.getDigits(num, "", 15000)
consoleLog("info","Got '%s' digits from user.\n" % digits)
if digits == '':
# Invalid call
if invalid == 3:
consoleLog("info","Three invalid
attempts!!\n")
session.streamFile("/usr/local/freeswitch/sounds/en/us/callie/misc/8000/invalid_extension.wav")
session.hangup()
sys.exit(0)
else:
session.streamFile("/usr/local/freeswitch/sounds/en/us/callie/misc/8000/invalid_extension.wav")
get_number(session,invalid + 1)
else:
consoleLog("info","Got a valid number: %s,
proceeding...\n" % digits)
return digits
def handler(session, args):
session.streamFile("/usr/local/freeswitch/sounds/en/us/callie/ivr/8000/ivr-please_enter_extension_followed_by_pound.wav")
numberToDial = get_number(session,2,num=10)
consoleLog('info','Got 10 DTMF digits. Writing "1" to file...\n')
fo = open('/tmp/dtmfData.csv','a')
fo.write('"1"\n')
fo.close()
# Do some stuff & wait for SIPP to hangup
session.streamFile("/usr/local/freeswitch/sounds/en/us/callie/ivr/8000/ivr-please_enter_extension_followed_by_pound.wav")
session.streamFile("/usr/local/freeswitch/sounds/en/us/callie/ivr/8000/ivr-please_enter_extension_followed_by_pound.wav")
return
- DTMF senario file:
- # cat dtmfSenario.xml
Cheers,
Michael

Hi Anthony, Thanks for the input. I will try & reproduce the problem & give you something more concrete to work with & log it in Jira.

Re: [Freeswitch-users] DTMF Digits Lost when Under Load
That's a pretty small problem description to be so sure about something. It would probably be better to capture some evidence of the exact problem you are having since we are using computers and we need to see the computers in action doing something specifically incorrect to diagnose any sort of problem. Take the time to describe the origin and destination of your calls, the call flow, the hardware in use on both ends of the call, detailed console logs on debug level, (maybe even uncomment the 2833 debug ifded in switch_rtp.c) and gather something to go on besides "I seem to be losing dtmf) maybe a packect capture of the networking interface on both ends of these calls. Also problems should be reported to http://jira.freeswitch.org not this mailing list. Save us a step if you report a jira and provide all the info above or we will just have to ask for it again.

[Freeswitch-users] DTMF Digits Lost when Under Load
Hi All, I have an issue that when my call volumes on my FS IVR box > 30 calls DTMF digits are lost (using RFC2833). It is definitely load related as it all works perfectly under 30 calls. Any pointers or a solution to the problem?
