SINA for Large Enterprise

1.Check whether the inbound routing configured correctly.

2.Check the sip server port of E1 voice gateway used for connecting with SINA.

3.check whether there is a dot after number prefix, such as “4.” , if there is, please remove the dot, “4” is ok.

Check if the “call-id-in-from” parameter in gateway you created is true , if so, change it to false. Otherwise, the extension number is sent to the line side, but the line side cannot recognize it, resulting in the situation of not being able to call out.

1. In “Advanced-SIP”, check the default sip profiles to see whether “inbound-codec-prefs” is enabled. Then click restart to go into effect.

2. In “Advanced-Modules-Configuration-Modules，make sure the “mod_av” is enabled.

1. The IP address, netmask and gateway on ge0 port of E1.

2. The IP address, port and SBC address of SIP relay of IMS.

3. The country calling code for number transformation.

The call from the E1 line is usually a direct call to the corresponding IP phone. So, the destination of the incoming route should be set to “Extension”. Then, to make a number modify. The advanced function of the extension is related to the local extension, or it doesn’t work.

1. Check the IP rules in the IP group of the E1 gateway to see whether the ringback tone setting is adaptive. If not, change it to adaptive.
2. Turn the VoLTE off on phones.
3. Take a packet capture.

1. Speed dial with adding ‘#’ is default in FXS gateway, if want to without adding. Add a rule of dialing rules of your own.
2. For IP phones, shorten the dial time on phone setting. 

Upload a customized sound in “Media Files”.

Find the absolute path of your sound, and copy that.

Create a number for transfer. And create a route for this number. Select the destination as system, enter the text like “playback /absolute path”. There is a SPACE between playback and /.

Create a number for transfer. And create a route for this number. Select the destination as system, enter the text like “ivr + ivr identifiers”.

The reason is the default maximum number of calls is 3 times, as long as there are 3 times of no answer or rejection, goes into idle automatically. You can change the maximum times to big enough, like 9999999999.
