Hi team,
My environment is as such: Lync connected to Avaya Communication Manager via SIP trunk and ISDN-PRI from Avaya Communication Manager out to the PSTN. We are having issues with 911 where the service provider is seeing the calling party information with a leading 1 and we simply need to pass the 10 digit number. I have seen documentation on the tandem-calling-party-num table to manipulate calling party information but haven't had any success. What I did on that form was CPN Length = 11, CPN Prefix = <calling party information passed from Lync via SIP trunk>, Trk Grp = ISDN-PRI to the PSTN, Delete = 1, Insert = <blank>, Number Format = ?.
Any ideas on how I go about stripping the leading 1 to make my service provider happy?
Thanks and regards.
