Outbound Callerid

10 years 7 months ago #7490 by dakudai

I had implement a system by openvox D410p with asterisk 1.4 & zaptel 1.4 & chan_ss7 1.3.
It works very well!

I set my caller id as "131415" for example,
when system outbound to agents via circuit(TELECOM operate,ISUP).
Agents' mobile phone always show the caller id "0131415" .

I have modified the configration in ss7.conf about subservice and noa...
but caller id still shows "0131415".

Can anybody help me?
Thank you!

If you confirm the nature of your called number is subscriber, please modify l4isup.c in chan_ss7.
Find the function "isup_called_party_num_encode", then change like this:


param[0] = (is_odd << 7);
if (pvt->link->linkset->noa != -1)
param[0] |= (pvt->link->linkset->noa & 0x7f);
/* param[0] |= (is_international ? 4 : 3); */ // Comment this line
param[0] |= 1; // Add this line
param[1] = 0x10; /* Internal routing allowed, ISDN number plan */


Test it then tell me the result, if you have any problem please feel free to contact me.

Thanks! Denins,

I've modify the file, re-compiler and restart asterisk....

Unfortunately, It seems not work!

The CLI still shows "0131415" .
Should I upgrade chan_ss7 from 1.3 to 2.0 ?

Please ask your Telco about this problem, they will tell you why your number
change to "0131......", then we can decide what should be modified
