Hi

We are migrating our OfficeServ 7200 firmware 14.06.05 V4.80 from ISDN to SIP trunks.

We are taking it step by step by setting up the trunks, then moving one set of ISDN's over then the other set.

We present one single outbound number for all calls (despite having DDI's for most extensions). We will initially route all outbound calls through the SIP trunks however we will initially be assigned a random number for the outbound calls but don't want to present this when calling. Our SIP provider says that it maybe best to see if we can present a different number using our PBX.

Can I do this with our Officeserv 7200?

Thanks in advance.

You can have the system present any number you want on any trunks you want.

The OS7200 has several CLI tables you can assign to different services (in your case you can use 1 table for the ISDN and 1 for the sip)

It all depends on what the carrier wants to see.

I know here some carriers require you to register to prove ownership before they'll let you send another number, but they "overstamp" your number onto their number, others will let you send any number you want and they honor it.

Hi

Thanks for your post.

So using device manager I can include the outbound number in 3.2.5 Cli Ringing then on the BRI trunk data 2.6.7 I set Cli table to 1 and for SIP Carrier options 5.2.13 i set Send Cli table to 1


Many thanks

No, you would set SIP Send Cli table to 2
