Hello,

A few months ago we upgraded our server from Asterisk 1.8.22.0 on CentOS 5.9
to Asterisk 13.13.1 on CentOS 7. We are still using SIP not PJSIP. Since the upgrade our remote users’ conversions are choppy. Here is what my sip.conf looks like for the users with most problems:

[user-name]

type=friend

context=sip-phone

trustrpid=no

call-limit=2

callerid=”Mike” <1008>

disallow=all

allow=g726

allow=g722

allow=g723

allow=ulaw

allow=alaw

username=user-name

secret dtmfmode=rfc2833

host=dynamic

mailbox08

nat=force_rport,comedia

canreinvite=no

any ideas? Monitoring using CLI, I noticed the device always select ulaw for codec.

Thanks, Motty

  • What’s the device?

    What are its codec settings?

    What’s your available & used bandwidth on the server’s connection?

    Are all users affected, or only some?

    How many concurrent calls do you have going through the Asterisk server when they notice the problems?

    What’s the load average on the server while it’s handling these calls?

    Try turning on call recording on the server and see whether the recording is choppy as well as what the users hear.

    Antony.
