Hi everybody
I have a small problem. I have set up a callweaver server with two
SIP accounts. I call on one, callweaver pics up, checks the caller id
and if it's unknown then it asks for a pin, after the PIN I can dial
a number and it calls out on the second line. All works perfect from
mobile phones, but today I tried for the first time from landline
with the PIN. I just get to hear the message "login incorrect" at
first I thought it could be some DTMF problem, so I tried all 4 dtmf
modes but none solved my problem.
After thinking a bit about it, I'm no so sure anymore if it really is
a DTMF problem.
This definitely sounds like a DTMF issue to me. Are you saying you
have an SIP DID that you are calling in on? Or is there some kind of
FXO/gateway to the PSTN involved?
Yes I am calling from a normal (non sip) landline, to my SIP account
which is answered by callweaver.
It's the phone from the office where I have to press a button to
activate DTMF.
I have called myself on the cell phone and on my sip account where I
answered with my softphone just to check if I can hear anything when
pressing a key on the office phone and it sounds "ok" for me.
Since it's the phone in the office I'm not 100% sure if there is
anything else in between, any gateways or something like this. Since
I don't have landline at home I can't really try it. But I will check
in the weekend from a landline phone.
Before I implemented the PIN thing, I could use the landline phone to
do the same thing. I called my first sip account, callweaver picked
up, I dialed and it called trough the second sip account.
I'm not 100% sure, but ... when I dial the number, isn't this also
DTMF? If so, then my problem is somewhere else.
I suppose that is possible, but the DTMF theory seems most likely.
If there is a way to adjust the gains at a gateway that might help,
if you are using in band DTMF, make sure to use a quality audio
codec. I have had most luck with RFC 2833 which isn't in band.
I have tried rfc, in band, info and auto, all with the same effect.
Also, sometimes if you are using an DID from an ITSP this could be
there issue.
HTH,
