Third party Sip phones on Cisco CME call transfer restrict

Posted:Thu 24 of Jun, 2010 (10:45 UTC)
Using 2851 router with CME:
System image file is "flash:c2800nm-advipservicesk9-mz.124-15.T9.bin"
Version 4.1(0)
Cisco Unified Communications Manager Express
E1 ISDN to TELCO

I have few Cisco 7912 skinny and few non Cisco SIP phones. One of the 7912 is configured with multiple lines on it and it used like receptionist phone for incoming calls. Some SIP phones don t have access to E1 , other have . For those SIP phones with access to E1 I want to restrict ability for transfer to E1 trunk, they should have only local/…./ transfer. Only 7912 receptionist phone should have ability to transfer to E1.
So in final configuration any SIP or 7912 without access to E1 trunk should make call to receptionist and he ll transfer to E1.

I put under telephony-service
Transfer-pattern .T
For 7912 phones with access to E1 I make template with command:
transfer max-length 4
This is working fine, but I can not find similar command for non Cisco SIP phones.
