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

Hello.

      Did you have access to your providers server to make this change ?
      Where did you change it ? I'm confused.

      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 ?

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
