(only sysop, init.bcm)
Syntax: MYC(ALL) <call1> <call2> [ <call3> <call4> ]

Sets all calls of the BBS. Up to 4 calls can be set. If no call is set, the
call from BOXHEADER is used automatically with SSID 8 for <call1> and 7 for 2.
For outgoing forward the BBS uses <call1> with SSID defined with FWDSSID.
If this SSID is already in use, it will be incremented until unused is found.
The different BBS calls are:
    <call1>   login for user and BBS S&F partners
    <call2>   only for incoming user S&F
    <call3>   2. BBS call (if needed), no S&F (e.g. call of sysop)
    <call4>   3. BBS call (if needed), normal like <call1>

Examples:   "mycall oe3xsr-8" and "fwdssid 5"
             BBS can be connected from users and BBS with "oe3xsr-8", <call2>
             is set from BOXADDRESS with SSID 7 for user S&F outgoing S&F
