    543543For DTMF INFO, [http://www.pjsip.org/pjsua.htm pjsua] application supports sending INFO request with ''application/dtmf-relay'' payload, please see [http://www.pjsip.org/pjsua.htm pjsua manual] for details. Also ''pjsua'' is able to handle incoming INFO request. Please see the source code of pjsua application for more information.

     545=== What is the difference between proxy and outbound proxy setting? === #proxy-outbound 
     546 
     547The {{{--proxy}}} option in [http://www.pjsip.org/pjsua.htm pjsua] application corresponds to {{{pjsua_acc_config.proxy}}} setting in PJSUA-LIB. This specifies the route set that is specific for the particular SIP account. 
     548 
     549The {{{--outbound}}} option corresponds to {{{pjsua_config.outbound_proxy}}} setting in PJSUA-LIB. This specifies a global route set that is applicable for the whole endpoint (rather than a particular account), and will be used for all accounts in the application.  
     550 
     551When {{{--service-route}}} option (this option corresponds to {{{pjsua_acc_config.enable_service_route}}} setting in PJSUA-LIB) is enabled for the account (default is disabled), the {{{--proxy}}} settings will be updated with the content of {{{Service-Route}}} header in successful REGISTER response. In other words, if {{{Service-Route}}} header is not present in 2xx REGISTER response, the {{{--proxy}}} settings for the account will be cleared. 
     552 
     553Unlike {{{--proxy}}} option, the route settings in {{{--outbound}}} option are not be affected by {{{Service-Route}}} processing. 
     554 
     555Both {{{--proxy}}} and {{{--outbound}}} options can be specified multiple times in ''pjsua'' command line to specify more than one servers. 
     556 
     557When both settings are present, the initial total route set for a particular account is built by appending the servers in {{{--proxy}}} option '''to''' the servers in {{{--outbound}}} option.  
     558 
     559For example: 
     560 
     561Account A has the following {{{--proxy}}} setting: 
     562{{{ 
     563 --proxy sip:PA1;lr 
     564 --proxy sip:PA2;lr 
     565}}} 
     566 
     567Account B has the following {{{--proxy}}} setting: 
     568{{{ 
     569 --proxy sip:PB;lr 
     570}}} 
     571 
     572And the {{{--outbound}}} setting is the following: 
     573{{{ 
     574 --outbound sip:PO;lr 
     575}}} 
     576 
     577With the above settings, the initial route set for account A will be computed as: 
     578{{{ 
     579 Route: <sip:PO;lr>, <sip:PA1;lr>, <sip:PA2;lr> 
     580}}} 
     581 
     582While the initial route set for account B will be computed as: 
     583{{{ 
     584 Route: <sip:PO;lr>, <sip:PB;lr> 
     585}}} 
     586 
     587If {{{--service-route}}} option is enabled for both accounts, and suppose the 2xx REGISTER responses for both accounts do not have {{{Service-Route}}} header, then the route sets for both accounts will be updated to contain only the outbound proxy: 
     588{{{ 
     589 Route: <sip:PO;lr> 
     590}}} 
     591
