Rusty Newton updated ASTERISK-27079:
------------------------------------

    Description: 
I am getting an issue when SIP timers are turned on, could be related to use of external_signal_address

session_expires=1800 (30min)

According to my PCAP output:
* INVITE created for outbound call (session starts with timer set at 1800)
   * Correct SDP IP information is set
* 15 minutes in, new INVITE is send out
   * Correct SDP IP information is set
* Session timer expires (30 minutes), new INVITE is sent out
   * Garbage is set for SDP IP
   * Other side replies with 488 - Invalid SDP information
   * Call is terminated 15 minutes later by Asterisk

The invalid SDP:
