Hi there,
I'm having a very similar problem to the one described here: https://supportforums.cisco.com/message/3025521#3025521 however, the suggested solution doesn't seem to be effective for me.
In my setup, I'm testing a couple of SIP phones using the numbers 6900 and 7000. My SCCP phones are in the range 6100-6299. I've added the following transfer-pattern commands under telephony-service:
transfer-pattern .T
transfer-pattern 7...
transfer-pattern 6...
transfer-pattern ....
I also have the following SIP config:
voice register global
mode cme
source-address 10.1.254.254 port 5060
max-dn 20
max-pool 20
authenticate register
authenticate realm testdomain.com
create profile sync 0072582434522911
!
voice register dn 1
number 7000
call-forward b2bua busy 6201
allow watch
name Support
shared-line max-calls 16
label 7000
!
voice register dn 2
number 6900
name Test
shared-line max-calls 16
label SIP Test Line
!
voice register pool 1
busy-trigger-per-button 1
id mac DEAD.BEEF.0001
number 1 dn 2
dtmf-relay sip-notify
username test password test
codec g711ulaw
I can call from a SIP to SCCP phone without issue, but when I try and transfer the call from the SIP phone, the line goes silent and nothing happens. Transferring the call from the SCCP end works as expected.
Any ideas what the issue might be?
Thanks,
Brandon
