Figure 
 5-25: Source Phone Number Manipulation Table for IP -> Tel Calls Page  
 
•  Index #1 defines Source number manipulation of IP calls from Lync 
Mediation Server. All calls received from IP address 10.15.9.11 (i.e., from 
Lync Mediation Server) and the source number prefix begins with '+1', 
remove the ‘+1’ from the number. 
•  Index #2 defines Source number manipulation of IP calls from Lync 
Mediation Server. All calls received from IP address 10.15.9.11 (i.e., from 
Lync Mediation Server) and the source number prefix begins with '+', remove 
the ‘+’ from the number. 
•  Index #3 defines Source number manipulation of IP calls from Lync 
Mediation Server. All calls received from IP address 10.15.9.11 (i.e., from 
Lync Mediation Server) and the source number prefix begins with '1', remove 
the ‘1’ from the number. 
•  Index #4 defines Source number manipulation of anonymous calls from 
Lync Mediation Server. Anonymous calls received from IP address 
10.15.9.11 (i.e., from Lync Mediation Server) replace the ‘anonymous’ caller 
ID with a modified well-known number, i.e., a7192083390. This manipulation 
is performed to create a well-known number in the P-Asserted-Identity 
header. Without this number, the PAETEC SIP Trunk could potentially reject 
the call. See below (in the 
Source Phone Number Manipulation Table for Tel 
-> IP index #4) for the Source Number manipulation Tel->IP manipulation 
rule that restricts the caller ID for an anonymous call.
