Re: [Linphone-users] Cannot make outgoing call [SIP/2.0 513 Message too large]

[Peio Rigaux]

Hello.


I tried changing the MTU value in the config file with no success.
Did you have access to your providers server to make this change ? Where 
did you change it ? I'm confused.



It would be great to allow a setting in Linphone to change the max UDP 
length to possibly solve this issue.
We could eventually add it but it would nto be optimal, as we strongly 
discourage using SIP over UDP 
.


Unfortunately, some providers allows only UDP. Did you try reducing the 
number of activated codecs and disabling ICE to reduce the packet size ?

The same message is received in Blink. Twinkle and Zoiper can make 
calls fine.
