Ser with Asterisk

Hi All,

I have got success in making asterisk work with ser… But have a problem with Asterisk IVR and ser call forwading…

We use ser 0.9.6 for sip registration and asterisk 1.6 as pstn gateway and ivr…

we get a pstn call on asterisk, we play an ivr, we ask for extension number.. the call is forwaded to sip user on ser.. this works fine..
The issue is following...

if the sip user has forward no answer, then ser forwards the call to other sip user, this sip user answers the call, but on the asterisk side it gets timeout and again asks for the extension number…
But if its picked up by the first user, every thing works fine…

Can some one help on this issue…

Regards
Nischal…

You might need to increase the wait time in the Dial() application… is SER responding with a 4XX failure, or is it a simple timeout where asterisk is sending a CANCEL after X seconds?
