And what about the exit status?

What shell are you using?

Newer Korn, and Bash, shells have pipefail:
Code:
$ ls blah 2>&1 | grep .
ls: blah: No such file or directory
$ echo $?
0

$ set -o pipefail
$ ls blah 2>&1 | grep .
ls: blah: No such file or directory
$ echo $?
2

$ echo ${PIPESTATUS[@]}  # BASH - show the exit status of all commands in the pipeline
2 0

How to find the exit status of |
You could run it in a subshell and store the exit status in a file until it's needed.
Code:
Lois_Answer_Code=$((sipsak -vv -s sip:192.168.1.3; echo $? > status) | grep ... )
sipssak_exit_status=$(cat status)
