call

"CALL" as in to make a voice phone call: 

"CALL" as in "summon" or a church calling:

If you mean "call" as in cry out, or yell, then use the sign for "YELL (see below)."
If you mean "call" as in, "I named my dog 'happy.'"  (In other words, I called him happy"--then use the sign "NAME" with just a single movement instead of a double movement.

Other signs for comparison:

PHONE: (use a small double movement)

Call on TTY:

What if you mean call as in "yell" or to "call out?"

CALLED as in "named" or "christened."
Use a single movement version of the sign "NAME."
