CME transfer SIP call to SCCP phone on same system

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

Hi Alex,

Thanks for the response.   I added the config you suggested, but I'm still seeing the same behavior.  Any other ideas? 

Thanks,

Brandon
