Softphone using H323

rajadurai · 11-20-2006, 09:16 AM

Hello,

Now a days we are seeing softphones developed by different companies which used SIP as signalling protocol. can anyone tell me about the softphones which uses H323 as signalling protocol? can you please give the comparison of both the softphones based on performance, latency and advancements in future.

Thanks in advance

H.323 and SIP competed in the same space to become standards. It looks like SIP won and H.323 lost.

It's difficult to tell the future, but SIP has one heck of a lead right now -- and H.323 had a head start.

Any comparison that you read is likely to be unbalanced in favor of one of the two protocols. It's like the "Unix vs. Windows" discussion. :lol:

Here are a few to look at.

Thanks for your reply. I went through the comparison, but the comparison in packetizer.com tells that H323 is more better than SIP. Moreover I read in some articles that SIP will do well in case of NAT/Firewall. Is it true?

If it is true, how SIP works with VPN, Firewall/NAT?

That's their minority opinion. :p

Take a look at SIP, NAT, and Firewalls.
