On b-leg I have 3rd party eqipment (LTE base station @ ZTE) that does not support DTMF at all (INFO, RFC2833, inband).
Dialplan look like:

<action application="export" data="nolocal:dtmf_type=inband"/>
<action application="export" data="nolocal:asr_intercept_dtmf=true"/>
<action application="export" data="nolocal:execute_on_media=start_dtmf_generate"/>
<action application="set" data="bridge_early_media=true"/>
<action application="bind_meta_app" data="5 a b execute_extension::send_floor_notify_AT0 XML default"/>
<action application="bind_meta_app" data="8 a b execute_extension::send_floor_notify_AT1 XML default"/>
<action application="set" data="sip_h_Ptt-Extension=............................................................"/>
<action application="export" data="sip_bye_h_Ptt-Extension=............................................."/>
<action application="bridge" data="{sip_rh_Ptt-Extension=....................}sofia/gateway/ThruToEth1_ZTE_192.168.15.110/$1"/>
, but despite all this, DTMF are sent by means of INFO.
I need not to send DTMF to LTE BS at all or at least I need to use inband DTMF.

Is there any way to have more than one realm active for bda? I have
several realms that I use and I use bma for some keystrokes and bda for
others, whose functions may change, i.e. start and stop recording of the
call.
