Hello, I have synology NAS with Asterisk/1.8.13.1. I have a problem in setting up paging group. I have configured extension 6400 as the paging group number and added few phones to it. the IP phones (grandstream) are configured with auto-answer for intercom/paging. Whenever I call the paging number 6400 I get busy tone and “no response” message on the phone display. I appreciate if somebody can help. Regards, Hussein ---

Paging groups sound like an Asterisk GUI concept, not an Asterisk one. Try calling a single device with Dial and capture the SIP protocol with sip set debug on; it is very difficult to debug anything without hard evidence. ---

Why does no-one ever start at the beginning of the INVITE! RFC 3261: [quote]21.6.2 603 Decline The callee’s machine was successfully contacted but the user explicitly does not wish to or cannot participate. The response MAY indicate a better time to call in the Retry-After header field. This status response is returned only if the client knows that no other end point will answer the request. [/quote] The phone is almost certainly not suitable configured. If you sent the auto-answer header, this probably means you didn’t configure the phone to accept this security violation (if phones auto-answered by default, they could easily be used for bugging an area). ---

This appears to have come from the phone, not Asterisk. The documentation won’t tell you that it is a security violation, but that doesn’t remove the fact that forcing a phone to auto-answer creates a security issue. However, if the phone can auto-answer, it should document how to enable that, and I would very much hope it wasn’t enabled by default. ---

Hello, I am sure that the problem is in the Asterisk. I have tried many IP phones such as Grandstream, CIsco and various soft phones. However, I always get the same results. Thanks ---

That means app\_page isn’t loaded; or, more likely, wasn’t compiled. ---

I have Asterisk installed on Synology DiskStation. How can install paging module on it. Thanks ---

How did you install it originally. If from source, rebuild using make menuconfig to select the module. Otherwise you may need to contact the person who installed it or produced the packages. It looks to me as though you will need to contact Synology, as it looks like they installed it and it looks like the device is intended to be used as an “appliance”, not as a user programmable general purpose computer. ---

Thanks David, Yes, it is installed as an add on Synology appliance. I will contact Synology. BTW, I have installed Asterisknow on a virtual machine for testing and paging worked like a charm on all my grandstream and linksys phones. Thanks again.
