Opened: Oct 01, 2018
Severity: 3-Major

Symptoms

In MRF SIP ALG, the hairpin flag is part of the translation_details structure. Because a connection/translation might be used for multiple simultaneous calls, if any call is hairpinned, subsequent calls on the same connection will not translate SDP addresses.

Impact

Subsequent calls on the same connection do not translate SDP addresses.

Conditions

-- A connection/translation using multiple simultaneous calls -- A call is hairpinned.

Workaround

None.

Fix Information

SIPALG::hairpin and SIPALG::hairpin_default iRule commands to enable or disable hairpin mode added.
