 For 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.

+=== What is the difference between proxy and outbound proxy setting? === #proxy-outbound
+
+The {{{--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.
+
+The {{{--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. 
+
+When {{{--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.
+
+Unlike {{{--proxy}}} option, the route settings in {{{--outbound}}} option are not be affected by {{{Service-Route}}} processing.
+
+Both {{{--proxy}}} and {{{--outbound}}} options can be specified multiple times in ''pjsua'' command line to specify more than one servers.
+
+When 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. 
+
+For example:
+
+Account A has the following {{{--proxy}}} setting:
+{{{
+ --proxy sip:PA1;lr
+ --proxy sip:PA2;lr
+}}}
+
+Account B has the following {{{--proxy}}} setting:
+{{{
+ --proxy sip:PB;lr
+}}}
+
+And the {{{--outbound}}} setting is the following:
+{{{
+ --outbound sip:PO;lr
+}}}
+
+With the above settings, the initial route set for account A will be computed as:
+{{{
+ Route: <sip:PO;lr>, <sip:PA1;lr>, <sip:PA2;lr>
+}}}
+
+While the initial route set for account B will be computed as:
+{{{
+ Route: <sip:PO;lr>, <sip:PB;lr>
+}}}
+
+If {{{--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:
+{{{
+ Route: <sip:PO;lr>
+}}}
+
