Hi, I am first time FS user, so it is a bit confused with all the setup. For inbound calls, I tried to add a voicepulse.xml in the sip_profiles/external with the following codes: <include> <gateway name="voicepulse"> <param name="username" value="3334445555"/> <param name="realm" value="my_sip_provider.com"/> <param name="password" value="3334445555"/> <param name="proxy" value="my_sip_provider.com"/> <param name="expire-seconds" value="600"/> <param name="register" value="true"/> </gateway> <gateway name="voicepulse-backup"> <param name="username" value="3334445555"/> <param name="realm" value="my_sip_provider.com"/> <param name="password" value="3334445555"/> <param name="extension" value="3334445555"/> <param name="proxy" value="my_sip_provider.com"/> <param name="expire-seconds" value="600"/> <param name="register" value="true"/> </gateway> </include> ------------ and in the conf/dialplan/default.xml file I added: <!-- Dial any 10 digit number (2223334444) or 1+10 number (12223334444) here --> <extension name="Long Distance - voicepulse"> <condition field="destination_number" expression="^(1{0,1}\d{10})$"> <action application="set" data="effective_caller_id_number=12223334444"/> <!-- If your provider does not provide ringback (180 or 183) you may simulate ringback by uncommenting the following line. --> <!-- action application="ringback" /--> <action application="bridge" data="sofia/gateway/voicepulse/$1"/> </condition> </extension> ------------------ For inbound, I added <extension name="Voicepulse"> <!-- your provider or any name you'd like to call it --> <condition field="destination_number" expression="3334445555"> <!-- your DID for this gateway--> <action application="transfer" data="1001 XML default"/> </condition> </extension> ---------- And, if I dial 3334445555 from a softphone registered with my_sip_provider, I got the message to the voice mail of 1001 - the 1001 extension does not ring. And if from 1001, I dial some real number like 18188892345, I got the error: Invalid Gateway ... Cannot create outgoing channel of type [fosia] cause: [Invalid_number_format] ... Would someone please give me some help to set this up. I am a bit confused with these. Thank you
