How can I pass a # sign to my MGCP FXO port?

[kylebrogers]

CUCM 7.1.5 and a 2951 with IOS 15

Goal:  I need to be able to dial 50# and have that passed out the FXO port, including the # symbol.  

**I cannot use and FXS card or ATA because the intercom system cannot "answer" the call.  It stays off-hook at all times.

I have an MGCP-controlled FXO port tied to an intercom system.  All I need is for the FXO port to pick up and pass "50#" down the line to the paging system.  No matter what I do, I cannot get CUCM to pass the # to the gateway, only the "50".  So the user then has to manually hit # after connecting to the paging system.  This is for emergencies so we really don't want to require them to remember this.  I have verified with CCAPI debugs that the called number does not contain a # when it arrives at the gateway.

There is a CM service parameter that controls whether CUCM will leave or strip the "#" from the called party string. By default this parameter is set to "true". Which means the "#" is stripped. Go to CM service parameters and search for 'strip'.

Note that this is a system-wide setting and could affect other call flows. You want to pay particular attention to any route patterns (or translations) where you rely/allow inter-digit timeout. 

HTH.
