Call Forwarding

Hi guys,

I am wondering if there is anyway to setup a TA90x to take inbound calls and then forward them back out to a different number? this would all be over SIP. I tried creating a voice user that had call forwarding but that does not seem to work. Any ideas if this is possible?SIP

Re: Call Forwarding

Yes it is possible usually all you need to do is create a voice user with a forward.  I would start by checking with the provider and seeing if they rejected the call for any reason, make sure you have a fresh current call example when you call them.  If they never see the call you will need to provide a copy of your config with usernames and passwords changed, and the following debugs:

debug voice switchboard

debug sip stack messages

debug voice verbose

Some providers require extra steps for call forwarding since call forwarding makes the original inbound caller id the outbound caller id, some providers only allow outbound calls from numbers on their system.  Sometimes you can fix this by using a DNIS ANI Substitution and that will work, sometimes you may have to add P-Asserted Identity depending on the provider requirements. Usually the provider will give you the requirements for doing call forwarding, then depending on their requirements will depend on what exactly you need to change.
