[Serusers] Getting rid of SIP URI in Caller ID

Hi all, I'm fairly new to SER (just heard about it this afternoon), but I've already run up against a problem that's vexing me. We have a Polycom phone sitting behind a Linksys WRT54G router/firewall with DD-WRT firmware. This version of DD-WRT is the "voip" edition, meaning it has SER and rtpproxy installed to help ease NAT issues with SIP. No configuration of SER is necessary, we enter the WRT54G's IP address into the phone's outbound proxy field and it just works. The only drawback is that when using this method, the caller ID on an incoming call from the PSTN contains a SIP URI (in the form of sip:5551212@207.179.x.x) instead of a simple telephone number. Our end-users are pretty voip illiterate and thus haven't the slightest clue how VoIP works. They are only going to get confused when a SIP URI shows up on their caller ID instead of the actual PSTN phone number of the person who called them. How can this be remedied? I can't tell what version of ser is on this device because the -h and -V flags return nothing. (Probably to make it slightly smaller for the embedded platform.) The 'strings' utility wasn't helpful either. Attached is the ser.cfg that comes with DD-WRT. Any help is greatly appreciated. Let me know if I need to provide more information.
