Whether Linksys SPA-(2102|8000) can restore voice session after a fax t.38 sending?

Hello!

Whether Linksys SPA-(2102|8000) can restore voice  session after a fax t.38  sending?

I tried to send a fax (t.38) through the softswitch and directly. Fax pass, but voice session is not restored.
From debug it is visible that SPAs do not send rInvite.
If rInvite comes from the softswitch, SPAs sends <SIP 488 Not acceptable here>.

I used last firmware.

Thanks.

Just to verify the scenario. What happens here is that a Fax was sent and after receiving the FAX do you want to continue on making calls?  BTW what is the SIP Server that your using?

It is normal that after fax sending, the user wishes to learn result and to be assured that everything is all right. Yes I want that voice session was restored after fax sending, and it would be not necessary to do a new call.

I tried 2 scenarios :

1) direct ip call(sip) from spa2102 to another spa2102.

2) PSTN--(isdn pri)--cisco5350--(h323)--MVTS{MERA}SIP/HIT--(sip)--LinksysSPA2102.

Result identical. Session is not restored.
If in the second scheme to use other sip-gw (other vendor) session is restored also all normally.

I am sorry for my English.

Thanks.

This could be a product limitation. The best thing I Could recommend is to call the tech support group so they could replicate your issue.
