Is there a way to get the FS public IP replaced by a custom domain name in contact header using the dialplan? tried: <action application="export" data="sip_contact_host=test.domain.tld“/> ...not working <action application=„set" data="sip_contact_host=test.domain.tld“/> ...not working <action application="export" data="sip_invite_domain=test.domain.tld“/> ...not working <action application=„set" data="sip_invite_domain=test.domain.tld“/> ...not working <action application="export" data=„sip_contact_user=bla@test.domain.tld"/> ...not working <action application=„set" data=„sip_invite_domain=bla@test.domain.tld“/> ...not working only thing working is setting the parameter in gateway config, <param name="contact-host" value=„test.domain.tld“/> but this is not working for me because I need to do it dynamically in dialplan! Any hint for me? thank you! Roman
