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

[islisis]

Hi, just submitting this report regarding outgoing calls to a SIP  
provider in Japan (softphone.spc.brastel.ne.jp) through UDP (Core 4.4.21).

I can register and receive incoming calls, but can't make any outgoing  
calls.

The log states:

SIP/2.0 513 Message too large

I tried changing the MTU value in the config file with no success.

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

It would be great to allow a setting in Linphone to change the max UDP  
length to possibly solve this issue.

Thanks
