Hi, I am trying to register an asterisk (Asterisk 1) against another one (Asterisk 2). My problem is that the REGISTER message goes without credentials and the Asterisk 2 send a 401 message to the Asterisk 1. How can I configure Asterisk 1 to force it to send credentials? I have tried setting Asterisk 2's IP in the "realm" field of Asterisk's 1 sip.conf, but it doesn`t work.

Hi, I am having problems with an Asterisk with a Digium TE205P card. The issue is that the Ring Back Tone is noisy. I am making modem's calls and this noise influences on the initial negotiation protocol, so modems have to recall. My configuration is: Asterisk version: Asterisk 1.4.21.2 Linux version: CentOS release 5.2 (Final) Card: Digium TE205P

...default But nothing changed. I am thinking of upgrading Asterisk and Zaptel versions, but did you have any noise problem with TDE205P? or is there any option/command to avoid passing any audio until the call finds a free zap channel and starts to ring? Thanks in advance. Best regards Imanol

Hi, I'm using an Asterisk box with zap channel as a gateway between PSTN and an alarm receiver system. The alarm system uses Contact ID protocol. My problem is that the negotiation fails and I think that the problem is that "kissoff tone" is cut and the transmitter doesn't recognize it. Maybe the asterisk tone duration isn't long enough. I'm thinking about increasing
