When sipxconfig generates configs files for a Polycom they've based on some version of Polycom's sip.cfg and phone1.cfg templates. It would be useful for debugging Polycom issues if the configs generated by sipxconfig included the Polycom template revision number.

Here are examples of Polycom template files, and their revision numbers:

 [root@sipxchange polycom]# more /var/sipxdata/configserver/phone/profile/tftproot/sip.cfg
 <?xml version="1.0" standalone="yes"?>
 <!-- SIP Application Configuration File -->
 <!-- $RCSfile: sip.cfg,v $ $Revision: 1.233.2.32 $ -->

 [root@sipxchange polycom]# more /var/sipxdata/configserver/phone/profile/tftproot/phone1.cfg
 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
 <!-- Example Per-phone Configuration File -->
 <!-- $RCSfile: phone1.cfg,v $ $Revision: 1.83.2.2 $ -->
