PRI/ELD to SIP Migration

[nkillgore]

I am moving all of my lines to a SIP trunk.

What I would like to do is have the phone company move a few DIDs at a time in order to isolate problems if/when they occur.

I'm having some trouble figuring out how outbound calls work when doing this. I set up a new route patter for my cell phone number and associated it with the new route list. It works when I call it from one of the new DIDs, but when I call it from one of the old numbers, the call fails.

Lets assume that I have a partition called Local_PT with a route pattern in it of 9.1800[2-9]XXXXXX

Can I set up a new partition called Local_SIP_PT and put the same route pattern in it and associate that pattern with the SIP route list?

I hope this makes sense

Thanks,

No, you manage failover thru GW/trunks via route groups and route lists, not by creating the same RPs. That won't work.

If I add the SIP trunk to the route list used for everything else, will calls fail over to the ELD/PRI if they fail on the SIP trunk?

Yes, that's why you configure the trunks/GWs in a particular order in the RG/RLs, if you're not familiar with this, I'd recommend you to review the SNRD chapter on dial plan to fully understand this.

Hi ,

I believe the working is , create a local_sip_pt and local_css,  give that loca_pt to the Route pattern.  This Routepattern will point it to Route List, which has the Route Group, which has the sip trunk.

Call flow:

RP-->RL-->RG-->SIPtrunk-->CUBE-->SIP-->ITSP.  Give the local_pt to the RP and local_css to end devices.

Or I guess a better question might be, how do I make calls from the new DIDs go out over the SIP trunk and calls from the old DIDs go over the PRI

Hi,

Create 2 PT,

Local_SIP_PT

Local_PRI_ PT

Create two CSS,

CSS_SIP <---Local_SIP_PT

CSS_PRI <---Local_PRI_ PT

Create 2 RG

SIP_RG

PRI_ RG

Create 2 RL

SIP_RL <---SIP_RG

PRI_ RL <---PRI_RG

Create 2 RP

9.1800[2-9]XXXXXX <---Local_SIP_PT , SIP_RL

9.1800[2-9]XXXXXX <---Local_PRI_ PT , PRI_ RL

Assign CSS_SIP to all new DN

Assign CSS_PRI to all old DN

Hope this helps.
