3rd Party SIP Phone Intermittent, Configured as dial-peer

[benjamin99]

I am using 3rd party SIP phones that occasionally "time out" and need to be reset (unplug, plug back in) to start working again. They are configured as dial-peers. Is this the correct way to configure a SIP phone? Is there any logging information to troubleshoot with a dial-peer? An example of one phones configuration is below.

dial-peer voice 9999 voip
 destination-pattern 9999
 session protocol sipv2
 session target ipv4:172.10.1.99
 dtmf-relay sip-notify
 codec g711ulaw

I wouldn't say this is not correct way, but definitely not preferred one.

To configure SIP phone, you should configure voice register pool and voice register dn and let phone uses SIP REGISTER message to get registered with CME instead of creating manual dial peer directed to phone's IP address.
