Bug ID 1116941: Need larger Content-Length value supported for SIP

Last Modified: May 29, 2024

Affected Product(s):
BIG-IP LTM(all modules)

Fixed In:
17.1.0, 16.1.4, 15.1.9

Opened: Jun 17, 2022

Severity: 4-Minor


SIP MRF sends error 413 when the content_length value in the SIP message is greater than 65535 (0xff).


The SIP messages with content_length greater than 65535 can't be processed by the BIG-IP successfully because of the hard coded constraint on the SIP content_length


The SIP content_length has to be greater than 65535 (0xff) on SIP MRF configuration



Fix Information

Make the allowable SIP content_length dynamic with respective to the configured max_msg_size in the SIP MRF session profile configuration.
