SBC SIP Trunking Sample Configuration


The sample configuration below is  designed to be used as a basic voice configuration template for a SIP trunking application to a SIP PBX on an ADTRAN SBC Feature Pack router or IP Business Gateway. It is assumed that the routing features of the device have already been configured. For more information about configuring IP interfaces for AOS voice applications, see Configuring IP Interfaces for SIP in AOS IPBGs.


Before using the sample configuration, replace all the <PARAMETER> items with the correct values for your system.  accept $ should never be used on the grouped trunk to the provider as it can result in internal calls being routed to the PSTN.


For information on grouped trunk accept templates, see step 6 in Configuring the Switchboard and Dial Plan in AOS.


For information on how to access the command line, enable prompt, and configuration mode, see Accessing the Command Line Interface in AOS.
