hi,

we are doing a lot with freeswitch and everything works absolutely perfect.

the only thing we are missing, is a good support for fax over ip - may
it be for offering a fax-2-mail service or just passing incoming
fax-calls from our fs-servers to a "real" fax-machine.

now we have another server only for callweaver, which has a great
fax-support. if we send faxes from our fax-machine over our
sip-provider (who supports t.3 directly to the cw-server, all faxes
are beeing received and saved by cw. but if we send faxes over the
same sip-provider first to fs and then do a bridge to the cw-server,
all faxes fail.

we set <param name="inbound-late-negotiation" value="true"/> in
internal.xml and play with bypass_media=true and/or proxy_media=true
in the dialplan. it simply does not work.

i think and hope that there are some other settings i can change, so
that fs is nothing more than just a "tunnel" and let both sides
communicate with eachother?

does someone know callweaver and can tell me, if there are some
important settings to be set for making it work with fs in the middle?


thanks & kind regards
dennis

Dennis,

I've been playing with fs/callweaver for a couple weeks.

I have fs routing calls and passing them to callweaver. In proxy_media
mode it works perfectly in bypass_media mode it works only sometimes.

Are you doing an 'answer' on FS before you bridge the call?

Are you sure that the call is being put in proxy_media mode?

Do you have canreinvite=yes on callweaver set?


I also had to put the following in my extensions.conf:

exten => s,n,Set(SIP_CODEC=ulaw)
exten => s,n,SipT38SwitchOver()


Those are some of the things I played with to get it working.


Let me know how you make out. Fax over IP is an odyssey.

hi,

sorry for the late reply and thanks for the replies.

it working quite fine now. we still habe some problems, because we
have 2 nic's (internal ip/external ip). we have to find a way through
different ip-adresses, ip-areas, firewall and switch

or is there a way to make fs listen to two ip-adresses?


kind regards
dennis

I think you can do that by creating another profile.
