Hi. Im getting something odd happening when configuring parallel hunt groups on my uc520:
Here are the command's ive entered and the error output:
Enter configuration commands, one per line. End with CNTL/Z.
UC520(config)#voice hunt-group 1 parallel
Number 21 is not a valid voice register dn. Re-enter 'list.'
And here are the DN's im trying to use with this group:
ephone-dn 6 dual-line
call-forward busy 22
call-forward noan 22 timeout 10
ephone-dn 14 dual-line
call-forward noan 21 timeout 10
It isn't until CME 4.3 that parallel hunt groups is supported for SCCP phones. UC520 is only shipping with 4.2 and the latest version on Cisco Website unless changed today is 4.2.8. In this version and below it was only for sip phones.
However, you can use the bcast.tcl script that has been referenced on this site a bunch. Just do a search and you will find it. It will do what you are looking for or you can wait until Cisco finally decides to release the 4.3 version of UC520.
