NV3140eSBC +1 from endclient is stripped when routed to the provider

Greetings folks,

My customer (MS Lync) is sending me sip calls in a +1NXX-NXX-XXXX format through a NV3140eSBC, to my softswitch.

Lync Server sends +1NXX-NXX-XXXX for a long-distance call

NV3140eSBC send me a simple 10D call

Call fails due to invalid dialing pattern (i expect a 1NXX-NXX-XXXX or +1NXX-NXX-XXXX)

MS_Lync to NV3140eSBC

Re: NV3140eSBC +1 from endclient is stripped when routed to the provider

Hi Vince,

I had the exact same issue.

Just added the following to my config and it started working:

isdn-number-template 0 prefix "" plan 1 type 2 NXX-NXX-XXXX

Let me know if it does the same magic it did for me!

That ​might​ work but I doubt it. No PRI here, it's SIP-to-SIP.

I would try creating a separate voice grouped-trunk for the provider and the client, each with only the appropriate trunk.
