So my setup is like this:
Cisco SPA112 connected to a FreePBX server which is connected to a SIP trunk from Thinktel.
When connecting a generic analog phone to the SPA and trying to make an outbound call, it takes at least 10 seconds before it starts to ring.
I also have SIP phones on the network connecting to the same PBX and they do not have this issue. Is there maybe a setting in the SPA’s that need to be changed or is there something in the PBX?
Be careful of setting the interdigit timeout to 1 second, as teaching the senior citizens to dial “really quickly” will likely not work so well either. However setting the dial string to cover all likely calls preempts the need to wait for “timeout” whethere it is 10 or 1 second or the need for a terminating #
Which country are we talking of here? we can possibly come up with a “closed” dialstring to suit.
Do you use 10 or 11 digit dialing ?
Are 7 digit calls allowed ?
Are international calls (non NANP) allowed ?
How long are your local extentions and of what pattern
Can your clients call 0, 911 or any other “short codes” ?
[*#]XX (matches feature codes
|911 (matches 911)
|NXXNXXXXXX ( matches all external calls)
|[1-8]XX ( matches all extensions)
The local extensions not starting with 1 collide wiith the regular calls so if they mostly call externally then you will need to wait longtimeout to have any internal extension that does not start with 1 ring, using 11 digit dalling avoids that of you dont use 1xx for you extensions , alternatively stay wirth 10 digit dialing and limit all extensions to ^1X. , if you need more that 100 , then use 4 digit extensions
