Hey, without this thread you wouldn't have gotten to use that great line. Thanks for the chuckle! > The thread is no longer about help. It's a bitch and moan and > status report on BV. Actually there are a few asterisk issues mixed in there along with a VIOP service provider that has technical pains. The fact that asterisk doesn't periodically re-check or deal with multiple IP's handed out by DNS and register with all of them is an asterisk problem brought to light by the BV configuration. The other problems are more VOIP provider issues, but one that asterisk newbies might not realize would be problems before they put their money on the table and try to get asterisk running with a particular provider. Here is my checklist that I will use to evaluate future VIOP providers. * Does the provider give you the raw settings so you can use a generic SIP device (such as asterisk)? * Can the VOIP provider assign you a local telephone number or will people be forced to call long distance to reach you? * Does the VOIP provider have an 8-bit clean ulaw path or is one forced to use their choice of compression? * Does the VOIP provider try to hide their ping times by filtering ICMP echo-requests and/or echo-replies. # Does the VOIP provider filter all ICMP's at the border router because of some "security issue" involving copious hand-waving. * Does the VOIP provider have SRV records setup for _sip._udp.<company>.<topdomain> ? (Shame, shame on any provider that can't take the minute or two to add those DNS records!) * Does the VOIP provider have forward and reverse DNS entries in place for all machines that send packets to customers? * Does the VOIP provider have low delay times (say 20ms - 40ms) for SIP-pings to their server? (Asterisk issues: Asterisk could really have a yellow/orange/red alarm system for indicating when delay times are heading upwards and user's will notice and complain.) * Does the VOIP provider force you to mung your native SIP address and make it impossible for your SIP device to re-invite and cut out the delays associated with forwarding all packets through their server? * Does the VOIP provider allow you to inject your SIP name and number on a per-call basis? (Eg. Can family members have the sip name aka "caller id", indicate the real calling party's name?) -wolfgang -- Wolfgang S.
