Environment:Asterisk certified/13.13-cert1 PJPROJECT version currently running against: 2.5.5 Debian Linux 3.2.0-4-amd64Attachments:( 0) pjsip-log.txt
Description:When receiving INVITEs larger than 2848 Bytes (maybe a Byte more or less) the packet data gets truncated to this size.
This breaks large INVITEs as send, for example, by the JSSIP library.

How was PJSIP built? Are you using bundled or an external one?

This happens with the builtin and also with the latest external version.

We can bump it up further for the bundled (it's set to 6000 currently) but for external it will be up to the person building PJSIP to do so.
