We just installed an Asterisk 1.4 system and have a Polycom 501 phone we are using to test it. We have a PRI installed as well and it works well. The problem.... When a call is incoming, the caller id says: 9999999999 sip:9999999999 at 10.0.0.1 how do you get it to just say 9999999999 and remove all of the rest? Thanks
