Yealink Call Quality

[Incubugs]

Has anyone found that using the latest freeswitch 1.10.3 and up with yealink phones that they are getting jitter speech and even simple things like calling the voicemail the prompts are sounding a bit jittery too ? we have 4 different installs where this seems to be happening and i cant seem to fix it ..

Any ideas ?

which codec are you using, as i know someone having exact same issue

 

[Incubugs]

We are using PCMA and we was using g722 but it was worse with that active. Prompts seem to sound better using opus however the transposing when dialing out is alot especially as these are vm

This is definitely something to do with the new freeswitch version.. is everybody now using 1.10 or are you guys still using 1.8.7 ? i didnt have any of these issues on 1.8.7

our issue turned out not to be yealink related and we are running 3000+- yealinks
are you 100% sure it is the yealink
have you enabled rport?
sip tcp or udp?

Thanks for your reply m8,

rport is on and the phones are showing tcp in the registrations page ... What did your issue turn out to be, its driving me nuts

 

[andycol]

ours turned out to be queuemetrics hurting the server
change to udp and see if it helps

 

[Incubugs]

where would i change to udp m8 ? not done that b4

 

[andycol]

would be under the extension setting on the actual phone if i remember correct
also have you taken some sip traces

 

[Incubugs]

no not taken traces yet, i cant see a setting under extension settings ?

 

[andycol]

will be set as transport

 

[Incubugs]

ahh its in default settings , i will give that a try m8 thanks for your help
