Hi All,   We have a network with multiple SIP trunks. Incoming calls can be load sharing across these trunks. Outgoing calls we also load sharing across all these trunks (Circular setup) issue we have: Mobile calls  in via SIP Trunk A (CityA) --> CUCM --> Cisco Handset ->transfer out -> SIP Trunk B (City B) Does the CUCM has a feature when you turn it on.. it should remember where the incoming calls via what sip trunk so whenever we send the call backout it should use the same SIP Trunk?   if the CUCM doesn't have this feature, then we need to reserve lots of bandwidth for the RTP stream from SIP trunk A to SIP Trunk B   Many Thanks, Trieu         ...

Hi All,   Lately, I have been trying to implement a network with +E164 format. I found out that Cisco Australia Dialplan doesn't understand  \+61.@ I can see in RTMT the number has been converted to +61477386XXX the CUCM doesn't know how to route it.   Since Cisco talks up so much about localisation and globalization in their design. May I ask if they have built this \+61.@ format in their AUS dialplan? Normal calls work fine with normal pattern 0.@.  If i create a static route \+61.[0-9]! the E164 format call can out to PSTN. Please let me know if i've missed something in this configuration. many thanks, T.N     ... View more

Hi Every one I've been trying to do an exchange 2007 integration with CUPS 7.X but it was unsucessful I have followed the book from Micheal H Lou 1) upload the CA certificate to the CUPS server 2) set an email account with Exchange admin view only, this account also has received as enable so it can read all other people calendar 3) add gateway as exchange. The exchange server is reacheable and Certificate is verifed 4)set up the meeting in outlook and set it as busy 5)log into CUPC and they status display as Available. Problem 1) Found error 401 Authentication issues between the CUPS and Exchange Action: check the login as domain\cupsexch we even setup the Wedav as this login format to makesure we can login 2) error found 503 Service Available return from the exchange Open a TAC cas the TAC engineer has been veryhelpful he has spent two days working with me on this. However the issue remains the same In TOPIC search he has found similar case where they just enable Webexch and OWA to the login method domain/user and restart IIS to fix it. We have tried this and even set the default local domain on Exchange to be domain.lab and changed the login from the CUPS as a cupsexch however we didnt have any lucks. I hope someone out there that has done this integration out there can shed some lights on this issue below are the trace of the Presence server + IIS on the Exchange Many Thanks for your help, M ...
