Appendix A XECfgParm.dat File Parameters
Understanding the XECfgParm.dat File Format
SIP.naptr_record_locate
(Added in Release 9.8(1))
Specifies the type of query the Cisco PGW 2200 Softswitch
uses to determine the preferred transport protocol of a
remote proxy. The Cisco PGW 2200 Softswitch uses the
query result for outgoing SIP trunk groups with the
siptransportmode property set to Dynamic.
Valid values:
• 0 = The Cisco PGW 2200 Softswitch uses UDP
transport and a UDP SRV query to determine the remote
IP address.
• 1 = The Cisco PGW 2200 Softswitch uses a DNS
NAPTR query to determine the preferred transport
protocol and a DNS SRV query to determine the remote
IP address.
Default: 1
SIP.transaction_based_dns_query
(Added in Release 9.8(1))
Specifies when the Cisco PGW 2200 Softswitch sends DNS
requests for transport protocol information.
Note Do not add this property to the Xecfgparm.dat file
unless you need to modify the default value. If the
parameter is not present in the Xecfgparm.dat file,
the Cisco PGW 2200 Softswitch uses the default
value. We recommend that you contact Cisco support
before modifying this property.
Valid values:
• 0 = The Cisco PGW 2200 Softswitch uses DNS NAPTR
and DNS SRV queries for the first SIP message in a call
dialog only. The Cisco PGW 2200 Softswitch uses a
DNS A query for mid-call SIP messages. This setting
provides backwards compatibility for Release 9.7.
• 1 = The Cisco PGW 2200 Softswitch uses DNS NAPTR
and DNS SRV queries for all SIP messages. This setting
provides RFC 3263 compatibility.
Default: 0
