Hi, If my application tries to REGISTER towards a SIP proxy that does not exist or does not respond, my client continue to resend REGISTER packages "forever". Should the SIP stack cancel the registration attempt after a specific timeout period or do I need to stop the register attempt my self? Is this a configuration issue that I have missed? cheers, Lasseo -------------- next part -------------- An HTML attachment was scrubbed...
