[asterisk-users] Sending SMS problems.

[Agazzini Maurizio]

Dear Sir,

I'm trying to configure the SMS capabilities of my provider (Telecom
Italia) with my asterisk. I tryed with a normal phone (SMSC number
42100) and all is working fine, incoming and outgoung SMS.

Now I'm trying to configure my asterisk for support SMS, the incoming
messages are working fine (incoming number 042111) dialplan match and
SMS recived. I'm getting troubles in sending messages...

I have done a lot of tests, mainly using a call file. Here the structure:

----------------------------

Channel: SIP/alice-voip/42100
Application: SMS
Data: 0,st
MaxRetries: 10
RetryTime: 30
WaitTime: 30

----------------------------

My test has been done with 2 lines, the first one is a VoIP line, the
second-one is an ISDN (with DAHDI). In all cases when sending the SMS
asterisk seem to don't detect the call pickup of the peer. Using the
SMSC number I get a log similar to these one (SIP):

-- Attempting call on SIP/alice-voip/42100 for application SMS(0,p(300))
(Retry 4)
== Using SIP RTP TOS bits 184
== Using SIP RTP CoS mark 5

(ISDN)

-- Attempting call on DAHDI/g0/42100 for application SMS(0at) (Retry 4)
-- Making new call for cr 32786
-- Requested transfer capability: 0x00 - SPEECH
-- Channel 0/1, span 2 got hangup request, cause 16

As you can see in both cases the SMS App isn't launched. I tryed all
app_sms loptions (p,t,s,a) but seem not an app_sms problem.

If I change the SMSC number and I put my phone number I get that:

-- Attempting call on SIP/alice-voip/XX for application SMS(0,p(300))
(Retry 4)
== Using SIP RTP TOS bits 184
== Using SIP RTP CoS mark 5
sms argc 2 queue <0> opts <p(300> addr <> body <>
 initial delay 300ms

The SMS app is launched... The pickup is detected only if I call another
number and not the SMSC one!

The SMSC number is correct, it's working with a normal phone and I can
call it by hand.

Any ideas?

Thank you in advance.

Maurizio

PS: I think can be a stupid error of configuration, but I can't figure
out by myself...
PSS: anyone have experience with SMS over SIP (MIME type vnd.3gpp.sms-tl)?
