Alright, I am basically cheap, and I have a cellular plan which allows for free incoming calls (Nextel). I was wondering if there was any way to do sort of a dialback trick in the extensions.conf. I call into the system from my cell phone (maybe via DISA), I dial an internal extension, and dial a phone number. Then * sends to my cellphone the number dialed thus giving me a in call on the cell. Or maybe have a call back with a DISA and then just dial my phone number I am trying to reach. Just a thought! Kim Callis -------------- next part -------------- An HTML attachment was scrubbed...

From there you can drop a sample call in the outgoing queue and then answer the line long enough to hang it up. This should make your outgoing call be about 1 second long, and allow you positive knowledge that the asterisk system received and acknowledged your call. The sample.call file can call you back then and drop you in a context where you can access anything you are interested in. See easy. -- Steven Critchfield <critch@basesys.com>
Hey Kim! I used to run that scam myself! You go! Back in the day, actually, I had our legacy lucent merlin phone system wired up to a modem on a webserver which could config it. And with some voicemail tricks and the like, it was possible for me to visit a little WAP site on my phone, and have it dial the number and bridge the call to me. In asterisk it would be a lot more graceful. You could build a little script to look for a two-way message from you and use the outbound call spool to set up a call.

Hi all, We're currently running a PSTN -> SIP gateway with Asterisk. We also run IAX/SIP -> PSTN. We have performed a test where the call is routed UK PSTN -> Digium E1 card -> Asterisk GW -> SIP G.711 -> FWD -> X-Ten softphone There is no echo at the softphone end, but severe echo on the PSTN side. We've also performed a test BRI PBX -> AVM Fritz CAPI -> Asterisk -> IAX -> Asterisk GW -> E1 -> UK PSTN Once again, no echo at the BRI side, but some echo at the UK PSTN side. We do have echocancel=yes / echocancel = 128 on the Asterisk machine with the E1 card. Is there any other options we can turn on / look at to test this? Also, are their any 'README's which document the best usage of the options in (for example) the zaptel makefile for MMX and more agressive echo cancel etc. We havnt tried these yet as we were unsure of any caveats?
