SRST SIP Phone PLAR Configuration

[Bryan Geoghan]

We have a customer that has Cisco 8811 phone and when connected to CUCM, it does a PLAR when going off hook and dials the PLAR extension. Is there a way to configure PLAR for the same 8811 SIP phone when in SRST?

1) You have to use command trunk <PLAR Number> under the e-phone in SRST. So for this configuration to work you have to define the phone with MAC in STST Configuration.

Haris,

That is for the SCCP version of SRST, not for SIP phones operating in SRST mode.

[HARIS_HUSSAIN]

For SIP Phone use the Barge AutoDial Feature

enable
configure terminal
voice register dn dn-tag
number number
intercom [ speed-dial digit-string] [ label label-text]
exit

Refer Below For More details

Will that work during SRST mode?
