I have an IP Telephony setup with CME 9.x.we are having 8961 SIP phones.
We are facing transfering issues when one call is on hold.Normal transfer is working fine.
For example Ext. 100 getting incoming call from Ext.200 and put on hold ,getting second call from from Ext. 300 and needs to transfer to another extension say ext.400.
But could not able to do.
Is it because of the line status like in SCCP we are changing the normal line status to dual line and octo line.
How we can do for SIP Phones?SIP configuration mentioned below
voice register global
source-address 192.168.20.1 port 5060
authenticate credential 1 flash:cred1.csv
authenticate realm test.com
dialplan-pattern 1 17103... extension-length 4
create profile sync 0398924808651486
voice register dn 1
call-forward b2bua noan 3001 timeout 10
voice register pool 1
id mac xxxx.xxxx.xxxx
number 1 dn 1
username n password 1
Thanks in advance
