Hi.
First of all, I am so sorry, if I have missed an answer to this, but I really looked.
I am having a problem where some of the voicemail recordings are slowed down/stretched, or maybe is recorded at a wrong sample rate.
I’m using the following settings, and using real-time mailboxes.
[general]
format=wav
serveremail=[REDACTED]
fromstring=[REDACTED]
attach=yes
skipms=3000
maxsilence=5
silencethreshold=128
maxsecs=120
;minsecs=0
maxlogins=3
emailbody=${VM_NAME}&${VM_MAILBOX}&${VM_DUR}&${VM_CIDNUM}&${VM_DATE}&${VM_MESSAGEFILE}
emailsubject=Telefonbesked
emaildateformat=%A, %d. %B %Y kl. %H:%M:%S
pagerdateformat=%A, %B %d, %Y %r
tz=european
locale=da_DK.UTF-8
operator=no
nextaftercmd=yes
minpassword=4
sendvoicemail=yes
I’m storing the recorded messages in /var/spool/asterisk/voicemail.
I’m using PJSIP as channel driver, and running Asterisk 22.7.0.
I’m using two endpoint trunks, one for inbound and one for outbound traffic.
I haven’t heard any complaints from users about quality problems during calls at all.
I have checked for RTP jitters, and I’m not finding any, and I have also checked TCP dumps for packet losses, and it’s barely noticable.
I’m running on Debian 12 in a Hyper-V VM, with 8 cores and 16 GB of memory, with an SSD SAN, and the cluster I’m runnig on is barely being utilized (I have it all to myself).
I am at my wits end and hope someone can help.
